Hello everyone, in this question they have asked that what is the major product in this following reaction.
00:05
Now, i am going to start with the mechanism here.
00:08
This is our substrate in this reaction.
00:12
Here we have ch2coooet and similarly here also we have ch2coooet.
00:25
So, it is going to be reacted with sodium hydroxide in ethanol and after that it is going to be reacted with h3o+.
00:38
In first step what happens, sodium hydroxide is a strong base.
00:41
It is going to be obstruct acidic protons.
00:43
Here we have two acidic protons.
00:45
So here, sodium hydroxide is going to be obstruct this acidic proton.
00:49
Here it produces anion.
00:51
In first step, here it produces anion.
00:54
Here we have c double bond o oet.
00:59
Here also we have c double bond o oet.
01:04
Here it produces anion.
01:06
In next step what happens, this anion is going to be attacked here.
01:09
This bond is break.
01:11
It moves towards the oxygen.
01:13
Here it produces inolate ion.
01:15
Here it produces inolate ion.
01:18
That is here we have c double bond o oet and here we have c o - and here we have oet.
01:31
And this bond here is directly bonded with this carbon.
01:35
After that what happens, it is going to be treated with here h3o+.
01:39
Here what happens, here o - is converted into oh.
01:43
So here it is converted into oh.
01:46
So here we have c double bond o oet.
01:52
Here we have c oh and here we have oet.
01:59
So here it is directly bonded to this carbon.
02:02
After that what happens, here oet is a good living group.
02:08
Here what happens, this is moves like this and this oet group is removed as etoh.
02:14
Here it produces minus etoh.
02:18
So here it produces ketone.
02:21
That is here it produces ch2.
02:27
Here we have c double bond o oet.
02:31
Then here we have ch2 c.
02:34
Here it produces c double bond o.
02:36
Then it is directly attached to this carbon.
02:39
So here minus etoh takes place.
02:41
After that what happens, it is treated with one equivalent of here it is treated with one equivalent of sodium ethoxide.
02:50
That is naoet.
02:53
Here sodium ethoxide is a strong base...
