The correct stablity order of following resonating structure is/are :

Options

A.
B.
C. `CH_(3)-Cequivoverset(o+)(O)gtCH_(3)-overset(o+)(C)=0`
D. `H-underset(..)overset(o+)(O)=C=oversetoverset(ɵ)(..)(N):gtH-overset(..)underset(..)(O)-equivN:`

Answer

A, C

Explanation

(A)
(Negative charge present on more electronegative)
(B) (Complete octet)
(C)`CH_(3)-Cequivoverset(o+)OgtCH_(3)-overset(o+)C=0` (Complete octet)
(D) `H-overset(o+)underset(..)O=C=oversetoverset(ɵ)(..)N:gtH-overset(..)underset(..)O-CequivN:`
(Neutral structure are more stable than charge resonating structure)
