Compare the stability of the following structures
Ya thats correct.As number of alpha hydrogen around alkene increases stability of alkenes increase.
And the 1st compound provided is diene which are very unstable..
yes, answer is correct.But why c more stable than a.Please explain
Why diene is unstable?
This compound A is actually cumulated dienes which have a very high energy and thus highly unstable.Also rotation around Pi bond is not possible ,which may lead to more instability..
