In this question we have to find the starting material for the given reaction.
00:04
So what is the reaction here, the reaction given to us is, we have a 6 member ring, okay.
00:13
This is a 6 member ring and we have a double bond here and two groups are attached here.
00:18
Now, here it is attached and down the plane it is attached, okay.
00:23
Here nothing is attached.
00:25
Now we will mark them.
00:27
So this is our first, then this is second, then this is the third one, this is fourth, this is fifth, this is sixth and this is the seventh one, okay.
00:40
Now these react with what? so initially it reacts with o3, secondly it reacts with what? it reacts with ch3 whole twice s, that is what, that is our dms and third it reacts with what? it reacts with znh2o.
01:03
So we get a, from a cyclic ring, the ring will break and an acyclic compound will form, okay...
