Thank you for the videos they are great. If you could make a play list of all the reactions, synthesis and mechanism videos I think it would help me not have to search through all the other videos that you have up.
at minute 4:30 when you write the structure (CH3)2 -- C=O-O there is a separation of charges and a positive formal charge on oxygen , my book write that as CH3 -- C(+) -- CH3 and only single bonds on oxygens (the last one has a neg formal charge) that that put a positive charge on the secondary C that became a more stable secondary carbotanion. Dou you agree with that?
Nucleophilic attack on central oxygen is not possible because of steric Hindrence of two oxygen atoms around it which also have lone pair of electrons and it means electron cloud around it which leads to repulsion of pi bonded electrons which attacks the oxygen but in the terminal oxygen (if you look at the resonance structure positive charge is possible in terminal oxygen by giving the pi bonded electrons to the central oxygen) it is possible.. so it happens like that...Hope it helps😊
Just a terrible explanation for tests LOL, let me explain this in a 30 second read. Whenever you see O3 you have to cut the double bond in half and just put two oxygens at each end from the cut double bond LOL!! Like C=O with O3 will be C=O plus O=O. looollz

Nice. Good explanation of the mechanism, step by step (extra points for color-coating ;D )

Thank the Lord for Khan Academy.
2:16 why phi electrons attack the unchanrged oxigen instead of the positively changed oxigen in ozone. Thanks.
Maybe to make cycle?

Thank you so much, this is very clearly explained from beginning to end. GREAT!
At 2:16 why the double bond attacks oxygen on ozone instead of carbon next to it
Thank you for this
ozonolysis is my favorite addition rxn
really helpful for high school students.Thank you so much sir!!
this is awesome!!! Props to you my friend!
Thanks very much my teacher, it's a well explained mechanism
Sei bravissimo! From Italy ❤️
What happens if the molecules are not symmetrical something like 1-methylcyclohexene?
+Dylan Dautel For that, you are going to get 6-carboxylheptanal.
After ozonolysis of alkene......ozonide is obtained.....then how to reduce ozonide....????
+hamza khan hydrolysis
+hamza khan Using the reducing agent DMS (dimethyl sulfide) (CH3)2S. There are more. You can add peroxide for oxidation to a carboxilic acid.
Why does the rxn start with an attack of a neutral oxygen? Shouldn't it start with the attact of the positive oxygen? "Necleophile to electrophile"?
very nice lacture
Good explanation 👍
What is the intermediate of 1-methylcyclohexene reacting with ozone?
great, but in the last example you've given, where is the third oxygen of ozone?
Bonds to the dms I think
nice thanks
why can't you explain the steps?
holy fuck theres too many arrows
I am lost loool
AMAZING :D :D :D
you are a saint
You forgot the last hydrogen Mr. Khan. But thank you so much!!
Why does the oxygen-oxygen bond break?
Becoz of random electron cloud shifting
Thank you very much.
Isn't he too fast
What? -_- this is one of the worst ones...
where the alkynes at homie
8:30 .....I quit!!🤒
where's the ozonolysis of alkyne?
worst _'_

But you might have to draw the mechanism and intermediates, then you are screwed.
