I was surprisingly able to understand just about every topic required for my first exam, EXCEPT Fischer projections. I watched so many videos and read through so many methods/examples on how to draw them, and nothing worked, however, this is quite literally the first and only tutorial I've come across that's actually enabled me to fully understand Fischer projections! Thank you so much!
Thank you...for those of us that are "rotationally" challenged, this gives us a way to do these problems without completely screwing up when exam time comes. Which is today. In 45 minutes.
In Turkish we say "iyi ki varsın". It's like "glad for your existance":D or "glad to know you". So, iyi ki varsın! You REALLY are a life savior. Thanks.
Dude. Your videos are amazing. I have an exam next wednesday and my god...you answered almost all my fischer projection questions. I'm blind in one eye so perception and spacial orientation is really hard for me. YOu make it all very easy. I subscribed to you and will DEFINITELY be using all of your videos to help me study. THANKS A TON MAN. Also- your R and S determination is freaking genius.
Thanks, i really needed this video! I have sat in the auditorium listening to lectures, and spent a long time trying to figure this out. But in the end it took only ten minutes 😀 This is the way to teach things!
life saver!! ty so much! The first step of conversion that my prof told us was to make it into an eclipse conformation which I cannot depict in my head so THANK YOU!
bruh wtf im from argentina, i have seen a freakin lot of videos of latin people and i didnt understand any of them. then i found this video, and now i understand everything. its amazing. and i aint an english expert or anything like that
Thanks!! After reading the textbook and watching my professors long 1-2hr video i still didn’t understand and ten mins of you explaining has helped me understand now! I appreciate it!
Thank you so much! it was super helpful, and very well explained, i'm from italy and it could really follow you step by step. you have been way more helpful than my book and teacher :)
Hi! Awesome Video, Super Helpful! One Question: When you numbered your carbons, did it matter which end you started at? 2 being the alcohol substituent and 3 being Chlorine substituent? If you started at the other end would it work as well - 3 being Alcohol and 2 being Chlorine?
Thank you for this video, all od my professors were teaching me this by looking at it from different sides and I was so confused, but I hope that this will save me on my tomorrow's exam :D
this is just a very good way to check my answer. in terms of understanding, it doesn't help. We need to know one of the two methods of converting a bond line to fischer which are either 1) rotate the molecule or 2) change the point of view of our selves(move our selves). The whole point of drawing a Fischer is to avoid coming up with those Rs and S configurations for compounds that have way too many stereocenters.
We know because carbon is tetrahedral; three of the orientations are known, and we can therefore deduce the fourth. For example the C attached to Cl, has two C-C bonds (in the page) and the C-Cl bond is a wedge. Therefore the "hidden" C-H bond will be a dash. For the C with the "dashed" C-OH bond, the C-H bond is a wedge.
At 0:30 you draw the hidden hydrogens. How do you know where the hidden hydrogens are pointing and whether or not they are ponting into the page, out of the page, or in line with the page?
in the fischer projection both the atoms on the horizontal line point outward right? but where exactly are they? how can they be at the same point? do they just stay side by side in 3 dimensional space?
So up to 3:14 in the video, you said that if the H was dashed, then it would be an R. however, since it's not, it's an S. Can you explain why we have to reverse it?
Glad you liked it or not? You can explore a short video of MOC membership benefits here, memberships are month to month, and you can cancel anytime: bit.ly/2YctxPb
Thank you so much for this video it helped me a lot. Just one question, if instead of a 2.5D line diagram im given a normal flat line diagram without the wedges and dashes how could i figure out the R and S configuration? Thanks for your answer!
Quick question, does it matter which to put at the top and bottom or not, you didn't cover that, I would've thought that H and OH we're supposed to be there since they're both dashed in relation to the strangling method so why arent they there? Or am I missing out something? 😩
I have one question. Why did you start labeling the carbon chain 1-4 on the right side and not the left? You didn't explain that, or does it not matter?
What if instead of thinking of it being reverse for carbon no 2 & 3, we actually flip positions of hydrogen so that now both hydrogens are on the vertical line...that would directly convert the fischer to the required configuration..so would that be correct ?
in fischer projection bonds coming out of page is horizontally represented bonds which are going in are represented vertically but what about those which are in plane of paper ?how they are represented in fischer projection?please please please reply THANKS

@@Uncle_Iroh65 yea and I'm still curious
@@sydney7462 fair enough
a 10-minute video that helps me more than my prof did in 1/2 hour
Prof. sucks
Thank you for the wonderful feedback
You are a life saver. My Organic Chem teacher at UCONN does not know how to teach.
Thanks so much. This is much more informative and useful than the Fischer Projections video that Khan Academy has on offer.
this is literally the best fischer projection video i've watched and the ONLY one i've understood thank you so much.
9 years later and I’m just sitting here spiritually crying in sudden understanding after hours of flailing helplessly
That's amazing, so glad!
I've watched soooo many Fischer projection videos and this is the one that actually worked for me!! Thank you!!
Thank you for the wonderful feedback
Thank you so much for breaking this down! It seemed so complicated in class, but it is actually straightforward.
You're very welcome!
This is the only video that has helped me with drawing Fischer Projections, thank you!!
In Turkish we say "iyi ki varsın". It's like "glad for your existance":D or "glad to know you". So, iyi ki varsın! You REALLY are a life savior. Thanks.

Thank you so much, so glad you found it helpful.
Thank you so much!! This is the first explanation that has explained how to decide which side to put everything on!!!
very useful video ,i have been struggling for many months and ur 10 mons video helped me thanks
Glad it helped
MAN thank you so freacking much. You have clarified so much in so little time. I wish you were my actual teacher. ❤❤
You are more than welcome!
You .. saved my life! I wish people could just explain this subject as simply as you do.
Thank you teacher you are smart . From Ethiopia 🇪🇹🇪🇹🇪🇹🇪🇹🇪🇹
Thank you so much, so glad you found it helpful.
I never thought that i would catch up this topic so easily.........But you have made it very easier....Thank You

Thanks....quiet interesting and beneficial rather than sitting in the class and wasting time.......
Thank you for the wonderful feedback
5:08 The arms are definitely strangling me xD Thanks a bunch!
ha ha...nice one
GREAT !!!! THANK YOU VERY MUCH !!! I don't have to worry about this now for Tomorrow's exam !!!! I cannot express my gratitude !!!
I’ve been confused about this all day. My professor didn’t explain it well and google didn’t help much. Thank you for this video! It was very helpful.
Happy to help!
I like you already and I'm not even done with the video😀. Very informative and your humor is top notch
Quite an innovative way to convert Wedge Dash to Fischer and beautifully explained too. Thanks.
Glad you liked it!
Thanks!! After reading the textbook and watching my professors long 1-2hr video i still didn’t understand and ten mins of you explaining has helped me understand now! I appreciate it!

amazing video, so much better than khan's. very clear and informative, thank you!!
one if the best teachers i have ever had .thanks
This helped more than many, many other resources including the "professor"
Thank you so much!
you just saved my life! i wish i found these videos sooner! thank you!!
Thank you for the wonderful feedback
clear, concise, and logical, just like science is supposed to be. You sir, should teach at my University.
Thank you so much! it was super helpful, and very well explained, i'm from italy and it could really follow you step by step. you have been way more helpful than my book and teacher :)
AHH I FINALLY UNDERSTOOD. YOU'RE A LIFE SAVER. Thank you so much
you are a life saver I am from south Africa
Thank you for the wonderful feedback
I LOVE YOU MAN..you've saved me hours
You are so welcome!
omg! I cannot thank you enough! I don't have a model kit, so I was going crazy trying to picture the 2D flipping around.
finally i understood the FISCHER PROJECTION... its quite easy after seeing this video.
I understood this SOO MUCH Better than my professor explaining it! He made me feel stupid explaining it to me.
just wanted to tell you that your videos and website are very helpful for jee-IIT aspirants
Hi! Awesome Video, Super Helpful!
One Question: When you numbered your carbons, did it matter which end you started at? 2 being the alcohol substituent and 3 being Chlorine substituent? If you started at the other end would it work as well - 3 being Alcohol and 2 being Chlorine?
Thank you SO MUCH for this video......you just saved me from a huge headache.my head thanks you too.

You're so welcome!
life saving videos for a person bad in organic chemistry.
##sharing is caring .so share more videos.wishes from india
God bless you, man. You saved me.
THIS HELPED ME SO MUCH FOR MY ORGO EXAM THANK YOU!!!!!!!!!
You are so welcome!
You are an amazing teacher sir!! Thank You so much for this. please keep on uploading!! :D
Thank you for the wonderful feedback
Thanks from France
You are very welcome to you in France!
Thanks man , i really did like your way my head always begin to spin when the prof begin to rotate the molecule .
It's very helpful . Thank you so much .
Thank you so much!
The molecule at the left has the H in dashes. Why are they not on vertical axis on Fisher projection?
Are you God?! I'm so blown away by 6 how much you make sense.

Thank you for that information
THANK YOU for the through explanation!
THIS WAS REALLY HELPFUL!!!!! THANK YOU!! YOU'RE A GREAT HELP!!!!
thank you, you just solved a mystery for me and luckely before my test :-)
Thank you for the wonderful feedback

Very helpful !! Thank you !
Thanks a lot sir for students like us.
You are great! Amazing job !!! Thank you soo much
Thank you so much, glad it was helpful!
Explanation at the begining was perfect but at the end was so confusing.!

So up to 3:14 in the video, you said that if the H was dashed, then it would be an R. however, since it's not, it's an S. Can you explain why we have to reverse it?
+Victoria Norelli because it is not dashed. easier to see with a physical ball and stick model

thanks Azain Ahmed ! glad you find it helpful!
you saved a nigga for his organic midterm, thanks.
Thank you so much for this video it helped me a lot. Just one question, if instead of a 2.5D line diagram im given a normal flat line diagram without the wedges and dashes how could i figure out the R and S configuration? Thanks for your answer!
Thank you for the wonderful feedback, and you are welcome!
thankkk youuuu!! i understand like A LOT after watching this video!! like thank you soo muchh!
wouldn't cl and h be swapped to fulfill the r rotation on
the fisher? if its drawn h-cl, doesn't it make the viral center have s rotation?
Why did you say that carbon 3's configuration would reverse to R? The hydrogen is already in the back, so the configuration is good as is.
@svitlana martynuk I've got the same doubt
This is incredible! Thank you so, so much for making this!
You're so welcome!
This is very helpful!
Thank you for the wonderful feedback
So why do you go from two coplanar atoms /molecules at first to 2 that are jutting out in the Fischer projection?
Jesus I flunked my exam on all these projections and RS applications.. tmr we have a test and this helped me a lot man
Thank you so much that was so helpful 🙏
Quick question, does it matter which to put at the top and bottom or not, you didn't cover that, I would've thought that H and OH we're supposed to be there since they're both dashed in relation to the strangling method so why arent they there? Or am I missing out something? 😩
It's just simply awesome. Thank you so much!
Thank you for the wonderful feedback
I have one question. Why did you start labeling the carbon chain 1-4 on the right side and not the left? You didn't explain that, or does it not matter?
+Amina 96 I was just using numbers to keep track of carbons, not IUPAC numbers. If I'd done it IUPAC it would have been from right to left.
In iupac OH is priortized, so you want that to be attached to the lowest numbered carbon.
a couple of videos later i totally understand it :D thank you !!!!
bro ur a lifesaver da
what if you dont know the configuration of the 4th group ..like if in carbon 2 the 4th group had been CH3 then what to do..pls tell
almost all your Fischer projection questions? if you still have more, let me know, I can make videos to address them!
Thanks for helping us❤.
Do methyl groups always go on the top and bottom of the Fischer projection?
violinsheets we have to find out the longest carbon chain for drawing the vertical line..
The most oxidized carbon goes on the top.
Thank you a lot, it helped me to understand Fischer projection. :D
You are my lifesaver. Thank you
Happy to help!
Thank you so much, subscribed 💜
Welcome!
What if instead of thinking of it being reverse for carbon no 2 & 3, we actually flip positions of hydrogen so that now both hydrogens are on the vertical line...that would directly convert the fischer to the required configuration..so would that be correct ?
So helpful video 🥰
Glad it was helpful!
in fischer projection bonds coming out of page is horizontally represented bonds which are going in are represented vertically but what about those which are in plane of paper ?how they are represented in fischer projection?please please please reply
THANKS
