- This organic chemistry video tutorial explains difference between chiral molecules and achiral molecules and how to find them by drawing a line of symmetry. It shows you how to identify the chirality centers or carbon atoms with 4 different groups as well as determining the number of stereoisomers using the formula 2^n where n is the number of stereocenters or asymmetric carbon atoms. This video also helps you to identify a pair of meso compounds which are identical to each other and a possess an internal plane of symmetry. It also discusses how to find a pair of enantiomers which are non-superimposable mirror images of each other such as your left hand and your right hand. Enantiomers lack an internal plane of symmetry.

why did i have to watch a 2 hour pre recorded lecture for this which was super confusing and now im watching a 10 min video and it makes so much sense
omg. the 2^n trick is incredible. professors really out here saying you just have to draw out or visualize everything...thank you.
It didn’t work on my assignment...
@@lianicole6456 2^n is not always correct it lists the max number of stereocenters but there could be less
@@markmarkson3047 yeah, as some could be mesocompounds
I watch your commercials all the way through and occasionally click on the sponsored links so you can get paid lol my way of saying thank you!!
@@b.chessman6049 What in the fuck is this supposed to mean
@@b.chessman6049 bruh what
I watch his videos with my TH-cam premium account so that he gets paid more.
@@ephraimgreyson1802 wth
Thanks for the reminder. gotta turn off adblock for this channel.
From the bottom of my heart, I say thank you for this video. You are God sent for those of us that have a hard time understanding our professors at school. They rush these topics so fast and when you ask questions is as if you are not supposed to be in the class. God bless you.
you're pretty amazing! thank you soo much for these! I've literally passed every chemistry class thanks to you and these videos! God bless you!!
0:27 What is chiral center/asymmetric carbon
2:25 Number of stereo isomer
3:05 Stereo isomers & Enantiomers
7:37 Molecule have plane of symmetric = Achiral
8:55 Examples
10:00 Mesocompounds
10:34 Enantiomers
Thank you
thanks!
thanks 😭😭
❤
I like your explanations! thank u so much.
but I really get confused searching for specific video, I think it would be better if u organize them in a playlist according to the topic ( isomers, ..) instead of a playlist for the whole organic chemistry
This was an AMAZING video and you explained it perfectly! Thank you so much!!!
It took a second to catch on, but I started to get it down during the examples. I’ve always loved organic chemistry, and these videos really help me understand all the confusing bits.
it took me 10 minutes to understand what my teacher couldn't teach me 2 lectures. THANK YOU
Same
You've saved my life from midterms. Thank you so much 😭😭💛
🥺
Thank you for breaking it down into secondary and tertiary. I never understood that part!
Thank you so much. I’ve been watching you videos heavily since I started Orgo in August 🙏🏽🙏🏽
There shouldn't even be 1 dislike to his videos
ur hard work is much appreciated
This is very helpful! Thank you very much. Keep them coming,
There are also some chiral molecules without a chiral center. For example dimethylallene.
Yes Allenes and cummulenes can be optically active if all four groups attached to them are different from each other
Thank you! I love you, you got me through chem 2 now organic yay
This is so much better than lectures. Thank god for this guy.
so far this is the best day of my life after spending 15-20 hours study this stereo chemistry. Thanks for saving my life. 10 days till the exam.
Did u pass my guy?
@@czeryneperalta1289 Oh Yeah. Haha. I am on the next one, which is Reaction of Alkenes and literally about to stress. I am going to look for those videos too.
This video is worth watching and definitely helps in classwork
Goodness, thank you so much for this video, you explained the concepts beautifully. Much love.
Wonderful explanation, easier to grasp the concept , thanks so much
I really enjoy your tutorials since High school... It is simple and can be understood clearly.
From Caleb at PACIFIC ADVENTIST UNIVERSITY.
You compare them very easily. I really appreciate you🙇♀️🙇♀️🙇♀️
Extremely helpful explanation, thanks!
Really good Orgo videos. Thanks, man!
This is the only tutor I’ve ever seen who has his own merch.
This channel is great in one way or another
I actually get it! Thanks alot for your amazing videos!!
Once again you came through for me. Thank you so very much .
This channel helps me a lot. THANKYOU SO MUCHH :")
2^n really saved my life thank you
i was here for my ochem class 2 years ago and now im back for my MCAT lol i love this channel
Thank you.
Organic chemistry learned❤
This makes so much more sense than my textbook!!
I have a question, does the inductive effect play a role in the difference between the two secondary carbons at 5:08 ?If not, can anyone give me the real reason?
Thank you the vedio is so useful for students👍🏼
thank u im from france and i have an exam in chemestry tomorrow u just saved my life , better than the others french professor
It's really helpful thank you ❤
always makes it super simple!
Love your videos. I got lost trying to figure out how many Hidrogens to ñout in the first Carbon
I felt literal relief when I saw you go over some of those examples
Did you get confused when you first learned it?
@@simplegirl9344 Absolutely, it through me off, but I felt better after the video!
Thank you so much for this tutorial
You are literally our savior lots of love ❤❤
extremely helpful, thank you!!
This guy is the only reason I have hope to live
I'm still a bit confused on how you can tell whether it’s an enantiomer or a meso compound. Do you maybe have a trick on how to see it?
thank you, you're a godsend!
thanks so much for helping me more then my scheme teacher
this vids are more productive than my whole ass 3 hours recorded lectures
What is the difference between asymmetric and chiral and symmetric and achiral carbon?
is this going to be on the midterm mr.white?
Isn't the carbon on the third number from the right(longest chain) also chiral? First molecule-One one end there is an ethyl group while on other bromoethyl. Can someone please explain.
Just a heartful thanku sir 🥺🙏🙏thanku so much
Awesom ..way to deliver lecture
That was very helpful.
You are the best thank you so much. Couldn’t wish for a better assistance. Thank you. You are doing great work
Helpful explanation..................................................
THANK YOU SO MUCH!!!!
you're the best , period !!!!!!!
The video was nice. Sir pls I don't know if you can add a subtitle I don't hear clearly what you say sometimes
love this video i reallyy learned
Is chiral centers possible only for haloalkanes ??? can it be possible for haloalkenes??
What is ssr and rrs...what dies he mean by those letters? Are they just to compare?
This is amaing! Thanks
I don't understand how you get the 2³. Please elaborate
I wish my professors would watch your videos just to learn how to fucking teach! you're awesome. thank you
Thank you so much sir ... ❤
This time i will sure crack the exam😢
I love this Channel
Well explained
thank you!
Are all meso compounds identical compounds?
Love your explanation. Do u make videos for physical chemistry too ?
ما في وايد قنوات عاليوتيوب تخدم هالمادة للأسف
Thank you so much 😍😍
Yup here i am again test in 4hrs😁✌️
Haven't even watched the vid but i Know I'll be a'cing it🏃🏾♀️🤦🤦
5:31 how having methyl affects it capability of becoming a chiral center?
Amazing
thanks!!!
Thank youuuuu !!!
What is s and r
Thanks 🙏
So for carbon to be a chiral center, it must have 4 different groups attached to it AND it must NOT have a plane of symmetry?
Yes, but keep in mind, if it has 4 different groups attached then that automatically means it doesn't have a plane of symmetry
Your a God send
Super cool☘️
hi, what does the S represent in the sterioisomers you drew?
It's the clockwise configuration based on the ordering of the different priority groups
THANK YOUU
At 2:13 why did he add Hydrogen as well?
Confused a bit at 8:17, you say that it cannot be divided as a mirror image but the way you drew it can actually be divided. If you lay down the molecule and cut it along it's middle axis like a sandwich you could split it. I think once you add in the H going away from or into the paper then you can on longer divide it in half. I think the OH group in that drawing should be coming out or going into the page to account for the implied hydrogen.
????? there's not another OH so how can we draw a line of symmetry anywhere lmao
@@zsib2085 You can draw a line of symmetry down the middle of 1 molecule and have 2 equal halves. You don't need 2 OH's to have symmetry.
1:32 i still dont understand having four different groups and 3:26 shouldnt that be in the second left hand since you mentioned mirror image

Can you be allergic to Chiral molecules?
How to get the number of steroisomer
at 6.22, I thought we found two chiral centers. how come the stereoisomers now became 8
There's 3. Carbon attached to OH, the tertiary carbon, and the carbon attached to methyl
bless you
Increase the output volume on your videos!
HI
shouldn't the two molecules at 3:38 be identical?
No because the bromine are on opposite planes. Look at the bromine bonds. If they were identical molecules they would both have either wedge bonds or dashed bonds.
Boss Bro!
Respecfully, I love you
