Hi, in this question we are given with 5 alkalihylides and we are asked to choose those alkalihylides which undergo fredilcraft reaction without rearrangement.
00:10
Here we can say that in priddlecraft reaction there is formation of carbocatinine and the rearrangement of carbocotion occurs when there is increase in sphero.
00:36
Stability of carbocetion.
00:45
The stability order is 3 degree is more stable than 2 degree and the least one is 1 degree carbogatine.
00:54
Here is the first structure that is ch3, ch2cl.
00:59
It is the structure of chloroethane.
01:04
This can only form 1 degree carbocetion.
01:14
And there is no possibility of rearrangement here.
01:18
Therefore, it will undergo riddlecraft reaction without rearrangement.
01:31
Now, in the second structure, we have two chlorobutane.
01:39
Here we can see that if we remove the seal, we will get a 2 degree carbocetion.
01:49
And there is no further possibility of rearrangement.
01:54
Therefore, it will undergo fidelcraft reaction without rearrangement...
