Which of the following is the least stable resonance structure of `CH_(2)=CH-CHO`

A

B

C

D

All are equally stable

Text Solution

Verified by Experts

The correct Answer is:
B
Among the given resonance structures
`overset(Ɵ)(C)H_2 - CH - overset( overset(oplus)O) overset(|)CH`
is the least stable one since more EN atom, O is carrying positive charge.
