Hello students, in this question we have to give the mechanism how this t is converted to v and t is converted to u.
00:08
At first we are going to consider the conversion of t to v.
00:13
At first we have taken the cis -butene which is the t.
00:19
So this will be our t.
00:22
This will react with the acetic acid.
00:25
That can be drawn as follows.
00:27
This double bond will attack the lone pair of the peracetic acid and thereby this bond will shift over here and this bond will extract this hydrogen.
00:37
And the remaining bond will shift to this double bond and forms a epoxide ring.
00:43
That can be drawn as follows.
00:47
Ch3 that lies below the plane single bond and ch3 and the hydrogen will lies above the plane and here will be our epoxide ring.
01:00
So this epoxide ring is again attacked by the acetate ion.
01:06
So that ho and here will be c double bond o and ch3...
