00:01
So, here we have been given with this reactant, this is connected to carbon which is connected to ch3, ch3 and chlorine and on reaction with ch3oh we have the following product.
00:20
Here is the required 5 membered ring, there is double bond, here is ch3 and here is also ch3.
00:31
So, we have to tell the mechanism of this conversion.
00:39
So, firstly if we see then we have this 4 membered ring connected to carbon, ch3, ch3 and chlorine.
00:53
So, here chlorine act as a leaving group, so it will leave and we will see the formation of this carbocation.
01:10
So, here we have 3 degree carbocation formed.
01:20
So now, here this carbocation will rearrange that is it will do ring extension because 4 membered ring has extra angle strain as compared to 5 membered ring...
