You’re very welcome dear Frank 💕
just wanted to say thanks. definitely reinforced my understanding in how the mech works. cheers
You are amazing, the best explaining any organic chemistry topics. Thank you so much!!!!!!!
You’re welcome! Happy to help! 😁 Where are you taking Orgo at?
Frank you are a life-saver! Getting me through Ochem 2

you are very detailed about the mechanism and thorough. Thank you! it's really important to understand "WHY" certain steps happen. you made it so clear..... thanks
Just thought I'd say you definitely made it easy! I was studying it in class and it made sense there too, but trying to do questions I got a bit confused again and yours definitely helped, especially because you used different colour pens!
You're also very easy to understand and follow along with, love the 'hello' at the start :)
You have made this so easy to understand! After revising for my exam and not remembering it at all, I have watched your series on Wittig Reactions and feel confident I will be able to complete any question they decide to throw at us!
Frank, the editing and structure of your videos has developed so nicely. I'm even further understanding my understanding of orgo. Best of luck with whatever you to choose do and thanks!!
Yayy, I might actually pass this exam now. Never thought i'd understand this reagent! YOU ROCK, THANKS!!
Oh my God, thank you so much for these videos about the Wittig reaction! (I know they're old, but I'm so happy to find them). You're a great teacher!
Thank you very much, love your explaination!! I will always remember the box-Mechanism ♥️
This is the first time to comment,,my lecture is a physical class but I come out of the class with zero content,, but this video was really amazing and easy for me,,keep up jonk
U're good, easy to follow. Keep it up
Thanks for the support Dominick In.!
you are an awesome tutor ! much love from Toronto Canada ✌😊
I'm a little late to the Frank Wong party, but this is the first time after 7 months in Org 1 and 2 I've had anything more than a tenuous grasp on a mechanism. Thank you!
Finally, some Ochem II material. Great as always....
Haha sorry, been held up and busy because of my Physics LA job and senioritis =X. But I do have some other Ochem II material (Acetals/Ketals + Imines/Enamines + H2CrO4 Chromic Acid Jones Reagent etc. in this playlist) th-cam.com/play/PLP0TLbeMObSych-cPedP1B1rk_bNVZZKT.html P.S. your fly is really freaking me out...lol
Great video Frank! Helped me a lot, thank you!
Frank ... thank you for your easy to understand explanations and examples! May I ask that when you give an example to complete, that you stand to the side of the white board please? It makes it easier to copy the diagram correctly in my notes, without having to rewind your tutorial. Otherwise, love the content you are sharing!!! x
+Sharon Doyle Thanks for the tip Sharon! I'll try to keep in mind when I make new videos :D Thanks for the support! I also have a $2.50 Lottery for Free Tutoring btw!

Thanks so much for sharing this video! You made it easy to understand and you are much more entertaining than my O chem professor!
Haha no problemo Jessica! :] I'm glad to hear, keep up your hard work!
Thanks a bunch! You’ve saved my life
Chayaporn Namwong FUNKY BOX 📦 FTW 😄
It finally makes sense! THANK YOU !!!
Yasmina Samaha Haha yay! That's awesome to hear! Funky Box!!!
powerful! following live from kenya
Wonderful explanation, I'm taking my DAT next month and although specific mechanisms won't be on the exam, this helps a ton with predicting products. Thanks and you're cute. :)
Glad I could be of help Dominique! Keep up the hard work. Let me get some discounts when you become a dentist ;) haha
Frank you are the man
:)was really useful , thank you
😭🙏🏻think i am gonna be able to do this
thank u soo much
@@yamnarizwan5657 awesome! You def can 👍🏼😁 you’re welcome!
nice one franko...thankyou
thanks! this was really helpful :)
very helpful!!!
You're the man Frank
This was awesome Frank! Thank You so much! My only question is shouldn't the final product be trans and not cis?
Good question Edgar! I'm unfortunately not too sure myself but I was just taught that as long as the Ylide doesn't have any resonance in it other than the P-C bond then you will have the Z- Product. But let's say there is a carbonyl C=O group near the negative carbon and can resonate with it then you would have the E- Product.
YOU ARE AMAZING GOD BLESS YOU
Please can you make videos on claissen condensation and adol condensation reaction. You're a live saver. I had be
Thank you so much!!! You're awesomeee!!! your explanation is way better than my professor lol
Thanks Chalermkwan :], I'm really glad to hear you found my video helpful. The Wittig reaction is actually pretty cool right?
@@OrgoMadeEasy Yes it is cool...I am from India...and this video is still helping after 5 years...Thank you Frank Wong Sir 🙏🙏🙏
So helpful, thank you.

Where do you end up using this in "work"? I'm entering college and am having a hard time understanding why one might use this later in life
You da real MVP
Hello sir ,could you please make a videos regarding retrosynthetic analysis of organic molecules
You are awesome!!!
If I put a negative charge instead of a double bond between the oxygen and the P on the first reaction would that be wrong? if so how do I know that a double bond is formed between the oxygen and the P?
Thank you
Thank you!!!!
top and bottom attacks of the carbonyl group to form the two alkene isomers?
thanks!
thank u so much
Very helpful! thank you :)
Bs chemistry
And every semester i watch dis video 😂 its been 2 yrs 4 semester and i always watch it
Thank you so much!!!
2:21 haha you're too cute i swear. You have no idea how youre saving me right now. Trying to learn from the textbook is painful.
thanks you soo much...really helped.....want more from u....:)
Thank u so muxh 😊👌
hey do you know how to determine streoselectivity of product from NMR?
thanks
Great video! but it isn't clear to me why the Z-alkene is preferably formed. Thank you very much for your contributions!
Adolfo Berro Pizzarossa I'm not quite sure myself but I know for sure if the Ylide is resonance stabilized then you will form the E-alkene and if there is no resonance stabilization then you form the Z-alkene.
Thank u soo much.. 😁
I LOVE YOU
lisa anne Thanks for watching! :] Hope you ace all the Wittig questions on your exams.
Do you know blackpenredpen ?
HEY WONG IM FROM SOUTH AFRICA U REALLY GOOD BUT DONT U HAVE VIDEOS TO DOWNLOAD I UNDERSTAND BETTER THAN THE TEXTBOOK
Hey there! That's really cool, it's awesome that I could help someone so far away :]. I unfortunately don't have any videos to download, but you can just watch all the ones that I have up here on my TH-cam Channel. Good luck!
you forgot to say why the Wittig reaction give Z or E alkenes (stabilized ylides give E alkenes while unstabilised ylides gives Z alkenes)
Hi, great point! To be honest this was never discussed in my class and I haven't been able to find much resources online which discusses this so I'm afraid I can't explain why behind this. =X
Frank Wong It is relatively easy as stabilized ylides that can form double bonds (for example with ketones) form already the E alkenes by steric effects and thats why they they form the E while unstabilized alkenes form the Z alkene kinetically (it have to do with the way they approach to each other, it might be easier to see using molecular orbitals)
Hmm interesting, if you have time you should do a quick tutorial video on it explaining with the molecular orbitals ;)
This reaction is not reversible, so why did you put two arrows?
Ah woops good point, the overall reaction and the very last step should have a single head arrow. But the other arrows should be equilibrium arrows. Like what you see here: upload.wikimedia.org/wikipedia/commons/thumb/c/c3/Wittig_Reaction_Mechanism.png/500px-Wittig_Reaction_Mechanism.png
Frank Wong True, The general scheme of the reaction and the last step in the mechanism need to have a single head arrow. It's important. :-)
LOL Finally!!
Your explanation is very good but please speak loudly because many times I can hardly hear you.
Marry me lmao

Just thought I'd say you definitely made it easy! I was studying it in class and it made sense there too, but trying to do questions I got a bit confused again and yours definitely helped, especially because you used different colour pens!
You're also very easy to understand and follow along with, love the 'hello' at the start :)
+Bethany Hunter Thanks Bethany! I'm happy to hear that my vid could help. :] If you're interested in helping support my channel and also getting a chance to win a free hour of tutoring with me check out my Patreon page: www.Patreon.com/OrgoMadeEasy. I have Lottery set up there for Free Tutoring :]. Best of luck studying!
+Frank Wong I had a test just after watching the video, and the Wittig question involved making an alkyne, not alkene in ours, which threw a lot of people off, so yes it helped me figure that one out. And the E/Z. I live in Australia and don't have skype, so probably wouldn't be much use to me.
All the best.
+Bethany Hunter Nice!! Way to figure it out! And ah I see, nevermind then. That's pretty cool though that my vid. could make it all the way down to Australia. All the best to you as well!
+Frank Wong Watching this from Aussie too haha. I almost cried not understanding the box mechanism when I was studying on my own. I gave up after two hours and watched your video, and it's perfect. Products are easy for me but the box mechanism was very difficult. I have an og2 exam tomorrow, wish me success! Thank you very much Frank!!!!!
