Carbonyl group has following resonating structures
(I)
The correct order of stablity of these structures is

A

`I gtII gt III`

B

`III gtI gt II`

C

`I gtIII gt II`

D

`III gtII gt I`

Text Solution

Verified by Experts

The correct Answer is:
B
The resonating structure with minimum or no charge is more stable . Thus , the stability of (III) is maximum . The structure (I) is more stable than structure (II) as the negative charge is power on more electronegative atom.
