Sir why you resperentace 2 electron in mechanism why not only 1 give electron in secondary carbon in the other way primary electron still and make bond with hidrogen?
you have not only saved my organic chemistry grade, but also my calc 1, general chemistry, and biology grade. this man is a LEGEND!! thanks so much for all your content!!
Let's take a minute to appreciate the effort our professors do to "teach" us this in just 3-4 weeks. It took him a whole hour to explain what just took our professors 4 weeks. "Good job" to our professors 🤕
count your blessings. My professor wants us to teach ourselves before we come to class. Then he will breeze over this so fast and add so much more on top of it.
I have a test coming up in a few days and I just watched ya videos and understood immediately like damn. Here I am at 4am in the morning understanding sh- better taught by you then my online class
I love how you managed to explain each reaction in simpler terms and STILL took longer to explain it than my professor did. To clarify, I'm complimenting you, my prof sped through all of this and I didn't even have time to digest it.
Thanks for this video I have a test on the reaction of alkenes on Friday, the confusing part is memorizing a reaction mechanism is hard and I will have to draw one on the test most likely, it could be a bromination reaction or an acid reaction
At 25:20, you said, "Make sure you know the difference in these 3 reactions," but I don't know how you knew the difference. Is there something specific that made you know it was anti for the second one and Markovnikov (staying on the double bond) for the last one? Maybe I'm just confused about the 1. and 2. above and below the arrow when it has a list.
You can tell the difference by the reagents he used. For the first it is an acid catalyzed hydration so you know that it is markovnikov addition. Also you can have carbocation rearrangement. For the second he uses the BH3THF complex so it’s a hydroboration oxidation. This reaction is regioselective for the anti-markovnikov product. Finally he uses oxymercuration-demercuration. It adds the OH group to the markovnikov position however it is different than the acid catalyzed hydration because there can’t be any carbocation rearrangement because there is no carbocation intermediate for that mechanism.
If Organic Chemistry is a video game, this would be the part of the game where the difficulty spiked for no reason. How did we go from balancing combustion equations to THIS 31:26? Did someone even playtest this? /j
For the problem that starts around 28:00 wouldn't the product have stereochemistry since their are two chiral centers? And would it be racemic since the H2O attacks the carbocation from either side?
4:58 pka of an alkene is about 35, and HBR is a strong acid. That first step is a proton transfer (acid/base reaction), not a nucleophillic attack. I think it really only starts to matter when you have, for example, a molecule with an alkene and an OH functional group.
hello can someone help me with this question TT 3-chloro-2-methylpentane reacts with sodium hydroxide in ethanol to produce compound A (major product) and compound B (minor product). Hydration of compound A produces compound C as the major product. a) Identify the structural formula for compound A, B and C. b) Determine the balanced chemical equation when compound A reacts with Baeyer’s reagent.
@23:50 Wouldn't it be just the iodine version that is formed because you need the HBr to protonate the alkene and NaI, although there's 2 equivalent, can only fully react with the 1 equivalent tertiary carbocation that is formed? The HBr is the limiting step. If there were 2 equivalent HBr and 1 equivalent NaI, that's when both the iodine and bromine version could be formed I think.
At 31:14 bottom right. Is the arrow pointing in the right direction in terms of the H20. Because it takes the H so the cyclohexane can have an OH and on the side the H20 turns to H30
This video is a good summary, just kinda unfortunate that hydrogenation isn't included (maybe in the full video on patreon). It is not the hardest of the alkene reactions, but surely an interesting one (with for example Pt/C or liquid NH (-78°) to ensure cis/trans isomers respectively)
In this case no because carbocations are more stable at MORE substituted positions. So it would be very very unfavorable to have a carbocation at a primary position. In fact, this is the most unstable carbocation and it is exceedingly rare that you will ever see a primary carbocation. Like once you start learning about substitution and elimination reactions, you'll see that if only a primary carbocation is possible it will always always always do an elimination instead of a substitution because it is much more favorable and fast to do an E2 elimination
Hey, I want to learn more about mathematics. I’m only in 10th grade, but i just want to learn a lot more about the subject. What’s the best book I can study to learn a lot more?
around 4:50 You said H goes to primary carbon? I was thinking in the reaction of an alkene with HBr, the hydrogen atom typically bonds with the more substituted carbon, which is a secondary or tertiary carbon, rather than the primary carbon. This is known as the "Markovnikov rule." or maybe I misunderstood. not sure

Fr ive been watching him sense high school just got done studying him for my micro bio exam now on to orgo 😂
When this man was in college, he taught his professor organic chemistry
😆😆😆👌
This man is probably teaching future organic chemistry teachers
😂😂😂😂😂😂😂
☠️
😂😂😂😂
You have helped me tremendously, I can't thank you enough for making all of these videos over the years.
it's like he knows what we want
I wish we can gift you the happiness and the relief that you give us after we watch your videos.
I'm having a test on Tuesday. So grateful that I found this channel
Bro how can your timing be so good?
I just got this for homework yesterday 💜

literally got taught this in one class
i learned more in 15 minutes than i did in 2 hour long lectures. thank you so much i have a test in the morninggg
me toooooo
I literally passed thanks for this guy. If you can notice, he sometimes mentions older topics that even he has not to say in video. Thanks man
Thank you for breaking this down - orgo has been so overwhelming but this made it clear how and when to check for steriochemistry
How did I get more out of the first 5 minutes this video than the last 4 weeks of lecture 🙃
I have a test coming up in a few days and I just watched ya videos and understood immediately like damn. Here I am at 4am in the morning understanding sh- better taught by you then my online class
My class recently just started this topic, thank you so much
I was trying to learn this since 1 year nobody could teach me so well as you
A lots of love and support from JEE aspirant
such a great video, I love the little explanations he does to reflect on previously learned subjects to remind us...
I love how you managed to explain each reaction in simpler terms and STILL took longer to explain it than my professor did.

Always ride on the top... You are such a amazing and interesting instructor 🙂
What a great teacher. Love your videos, they helped me a lot
What a productive 1 hour
If there is a heaven you are definitely going there.
3am and I am cramming with this.
Are you the ultimate teacher?
I love you!!!!!!!!!!!!!!! it took you 2 minutes to teach me this, my teacher and my books did not help me understand the basic

I finally understand everything. Thanks as always!
I wish this video had time stamps

Best Video on this topic
You are a great tutor.
You are always a life saver! Thank you for what you do.

I am about to fail my ochem midterm
How was the exam?
Fucking retweet Fr.

Dear stranger, thank youuuuuuuu
Sir plz make a video on the preparations too
ur a life saver fr ily
49:08 OAC is mostly used to remove the hydrogen not water
helped so much
This video is a good summary, just kinda unfortunate that hydrogenation isn't included (maybe in the full video on patreon). It is not the hardest of the alkene reactions, but surely an interesting one (with for example Pt/C or liquid NH (-78°) to ensure cis/trans isomers respectively)
In 1.08.52, when B have four bonds, its charge should be +ve or neutral like this? I have some doubt...
My MCAT studying has become a lot less stressful b/c of this man
Thank you so much goat
how do i know if i get the dash and wedge products (with charial center) or one product with neither dashes or wedges (no chiral center) instead?
Wait i get it!!!! only show dash and wedge products if its a charial center! duh!
Wow what the heck, my unit test on this is tomorrow
me with my alkene reaction exam in two days 😳😳
please where does it begin? i have an exam on Monday and I'm totally clueless on how to go about it
Very nice ringtone at 23:00😂
lmao yeag
Lmao😂
thank you so much
Can anyone tell me where he got the second O in his product at the top at 32:07?
Legend.
Love you bro. Thanks for these videos.
Sir can we make more than 1 mechanism for 1 reaction at Bsc level
tysm!
Why does the Br go on the primary C in the beginning?
thank you
when does markovnikov geochemistry occur?
I have a dihybrid exam tomorrow but I'll study this instead cuz i mean why not y'know
35:15 why do we convert pentane to heksane
At 9:36, is it possible that the 5 ring, will turn into a 6 ring (after a hydride shift to put the positive charge on the primary carbon atom)?
In this case no because carbocations are more stable at MORE substituted positions. So it would be very very unfavorable to have a carbocation at a primary position. In fact, this is the most unstable carbocation and it is exceedingly rare that you will ever see a primary carbocation. Like once you start learning about substitution and elimination reactions, you'll see that if only a primary carbocation is possible it will always always always do an elimination instead of a substitution because it is much more favorable and fast to do an E2 elimination
the carbocation would be directly on the ring, which (among other things) makes it unsuitable for a ring expansion.
Notification gang
✊✊✊
my noti do be 6 hours late uhm
couldnt the first word problem have 4 products instead of 3?
I love the video and I appreciate the effort but there are too many loooooooong ads, and it breaks my concentration
1:08:39
Is this really ethoxide or is it called propoxide ?
so is the problem at 16:15 stereo selective?
How do you make alkene from an alkane?
We alchile te amo eres un chingon explicando
Ignore this, this is for me 43:52
Can you doe aromatic reactions ?
Was once a student here👩🎓
Can you please do a video about name reactions?
thank u so much !
love the video .... hate the ads tho omg 20 ads at least lol
Hey, I want to learn more about mathematics. I’m only in 10th grade, but i just want to learn a lot more about the subject. What’s the best book I can study to learn a lot more?
Relax.
I was able to follow you up until 24:08 :(
🙏 nicely made..very informative
Is this O levels?
well, no
its more so the As and A lever stuff
Thanks❤
very nice
from iraq I want to say to my professor : watch this video please ...
Around 17 mins, i think you count the C wrong.
around 4:50 You said H goes to primary carbon? I was thinking in the reaction of an alkene with HBr, the hydrogen atom typically bonds with the more substituted carbon, which is a secondary or tertiary carbon, rather than the primary carbon. This is known as the "Markovnikov rule." or maybe I misunderstood. not sure
Markovnikov's rule is when the H goes to the primary carbon, and the halogen goes to the more substituted carbon.
I get having some ads throughout, but you literally have one every 4 minutes.
U block origin
Awesome 😁
cool, but so many adds
Does the goat reply back?
Apparently no
without you i will probably live in a cardboard box under a bridge.
