- Hey Hey! This is the Mechanism Walkthrough for Acid Catalzyed Hydration of Alkenes, a type of Additon Reaction. If you guys watched my NMR video series, guess who's backkkkkkk?! ;)
Unfortunately Cheyanne was too busy to help me actually film but her role in a previous video came in really handy for this video. Hope you guys like our little demo haha.

Acid Catalyzed Hydration Mechanism with any Strong Acid( Hydrochloric or Sulfuric ), and Water to hydrate our double bond. Markovnikov Addition
it takes me 7 years to find you... love your way of teaching!
Thank you so much!!! i basically went thru my lecture slide almost thrice times, but ended up i understand this from ur video! really helpful! appreciate it!
You’re welcome Elia! Glad to hear that! 💪🏼😊 where are you taking Orgo at?
I'm looking through your videos now, as I am currently in Ochem and we are going through allllll those different reactions and it just gets confusing but I like how you simplify it, telling us immediately what to look for to indicate what kind of reaction to expect..... I'll send some more feedback your way as I watch!
This guy is good. His silly analogies make it incredibly easy to memorize and recall steps.
Dude, I love your videos, clear explanation, it is a very good thing that your videos aren't long, which makes them less boring to watch, very very helpful. thanks a lot.
+sukina ikab Thanks Sukina :]
Hi! I'm in gen chem but your teaching style is great and I understand most of it :) I'm definitely looking forward to orgo
you're the best!!!! my chem prof is really scary so i don't go to her i just watch your vids instead!!!!!
Farheen Kadwa Haha thanks! I'm glad I could be a decent alternative ;). Profs usually end up nicer than they seem, although there are exceptions haha
man...ur awesome. I always watch ur videos. they really made organic chemistry easy for me.. so thank you and keep making videos....👍🤘
it's very clear....you teach all if & but in it which I got before watching these vedio.
if only i had found your videos sooner...my exam is tomaro sigh..still very helpful though u explained so clearly! thanks :) will be checking in on more of your videos :)
you were very clear..it all seems so easy now!! thank you
you did a GREAT job of clearing things up for me. My only issue was that I'm not able to see certain things you wrote clearly because they are tiny lol but LOVE your video and how you explain things. Thank you
All of your videos are really great.. thank you very much for doing what you do.. They are really helping me with understanding orgo 2
Thanks Christopher! I'm really glad to hear that they be of help :]. I saw your comment about Hydroboration and when I get a chance I'm going to see if I could do a video on that.
Thank you very much.. I understand the mechanisms a little better now, but every now and then I get stuck or mess up lol.. do you have any ideas on what I should do?
***** That's normal no worries. Practice and doing the same type of problem multiple times to see the different possibilities help a lot. And also make sure you understand the logic/reasoning behind each step in the mechanism. Otherwise you should be fine. :]
It really does.. for me the hardest thing is just trying to remember all of the different special groups and the mechanism they use to synthesize different things.. right now we're doing the synthesis and reactions of alcohols and ethers
ty for explaining every lil thing in detail for a noob
Currently saving my life !
Lyric Harris Haha anytime! ;)
these are awesome man, I love it!
Frank... you are effing awesome!!! I am soooooooo grateful for your videos!!!! ^_^
That was great!! So the H2SO4 was just another acid you could have used correct?
Correct! (Sorry about the late reply haha)
Thanks Sandyman! I really appreciate your support, I'm planning on spending most of my time making these videos once I graduate ;). Got any suggestions on how I could improve my videos? My most recent Acid/Base video best reflects my current work.
"Hi, I'm Flourine!"Oh my God I'm laughing like a fool. In public too!
+Christina Eldridge Haha #MissionAccomplished
You got a knack for teaching, pursue that
Thank you
Please do more, these are fire
hey Frank, your video's are awesome! really helpful. How old are you?
Michelle Victor Hey Michelle!! That's so awesome to hear, I'm glad they're helping you. I'm 21 lol and I've dedicated my life to creating this super resource for Orgo students everywhere. :D

Haha thanks Tyler! Glad I could help. :]
thanks, very helpful.
Hey there! Ah Gen. Chem my absolute worst nightmare haha. Thank you for kind comment, that's really impressive that you understand this already lol I feel like you're going to do great/like Orgo a lot! Best of luck with finishing Gen. Chem be sure to check out Vespr.org in case you need help. There's over 20 educators like me teaching it. ;)
Thanks it was helpful
What if we use D2O (Heavy Water) as a solvent??? What changes in the product do we expect???
BTW Ur Videos r just awsme!!!! ;)
mind blown! u really saved my life hahahahaha
Ezikel Reyes :] Glad I could help!
No problemo! My pleasure to make Orgo Easier ;) haha
Thanks! Haha I'm sorry, I didn't realize how tiny they'd end up :X hope I didn't make you squint too much. You can try full screen? lol. Your welcome and ty for watching 8mins and 51sec of me blabbering ;).
thank you for the vid!
Good video sir. It does need some vocabulary emphasis though. Call out your subjects and address them: such as "proton transfer" during the initial alkene double-bond breakage. "Nucleophilic attack" when the nucleophile/solvent seeks the most stable carbocation. This model is great but also mention to your viewers that when given a larger asymmetrical substrate, that if a new chiral center is generated, that a racemic mixture of enantiomers will be expected for the stereochemistry.
1Smoking Lizard Thanks for the feedback! Yup there's a lot more to discuss but I was just trying to focus on the more important parts and to keep the vocabulary simple. I will keep your feedback in mind though for future videos. ;)
Good points.
Ah I see, yeah I remember when they bombarded my class with like 20 reactions in 2-3 lectures and we were all like this --> O.O' haha. But thanks I'll be sure to keep giving you guys tips for recognizing the reactions :].
I am having trouble understanding what keeps the Cl(-) from quenching the carbocation. I understand water acting as source of elections due to the lone pair, but I don't know what prevents the ion from forming the haloalkane.
+Vassimau Ah so it's because there is soooooo much water since it is the solvent and it just out competes the Cl for attacking the carbocation. Yes the Cl does go and attack successfully sometimes but at a very low percentage in reality.
Thank you very much, you're videos are great.
Thanks ! :)
Haha yep, when HCl goes into a water to form a solution, the H falls off immediately and is picked up by H2O and then H3O+ is formed.
so what happens to the h2so4? o.o
i understand everything else but does that mean it doesn't react with the starting compound (2-methyl-propylene?) or the solvent (h2o)?
When the H from the catalyst bonds to the C would the bond not be dative as both electrons went to the O?
Hmm sorry I'm not sure what your question is JackSwatman can you clarify it?
thank you :-)
Would H2SO4 somehow react to turn into a H3O as well, or could it just react on its own?
awesome! Thank you :D
why would the neg charge cl not attack the carbocation but the neutral water molecule would attack instead.
Great question! So yes the Cl does have a neg. charge but it's actually quite stable in that form. It has a full octet of 8 electrons stabilizing the outer shell. Cl is also a halogen that is very electronegative and greedy with electrons. Oxygen in water however is a bit less electrronegative and more willing to share electrons to attack and form a bond with the carbocation. If it was a OH with a negative charge than that would definitely attack instead of water. :]
How about the configuration. The stereo center carbon would prefer R or S? or is it going to be half half?
Sorry, I notice the one on the left side is actually turning into CH3, but I mean if the original reactant is cis- or trans- CH3CH=CHCH3, will the newly formed chiral center be R or S?
john shiveley Hmm in that case, you would have to do an R/S analysis ranking the priority of the groups. It's not as simple as saying if it's cis it will definitely be R or S.
So it is random? It will form both products?
john shiveley Actually yes both R and S products should form since the Water can attack from either the front or back of the carbocation. So it is similiar to an SN1 reaction where you will get a mixture.
Thanks. Your video is really good!
I mean so the H3O, one of the hs is from HCl?
is there stereochemistry for acid catalyzed reaction
Wait so HCl just goes through the reaction or water too or what?
Why is the oxygen atom positive when it has 3 bonds?
This is kinda late but it's because the oxygen has 3 bonds and a lone pair so it has a formal charge of +1.
Formal charge= (valence e-) - ( lone pairs + number of bonds)
= 6 - (2 + 3)
= 6-5
=1
@@reirama475 Haha appreciate the reply! I'll be graduating for my bachelors this year :)
@@blingclem congrats!
I’m doing some review for an orgo exam coming up in a few days haha.
@@reirama475 Nice one, best of luck!
Wait so does HCl who
hahahahahahahaha
