Question

24. The least stable resonating structure is
(A)
(B)
(C)
(D
24 one plsss

Answer 1

Answer:

I think the answer will be c

Answer 2

Answer:

d

Explanation:

to check resonance stability first check number of pi bonds

B has most pi bonds so it is most stable

then check negative charge  placement. negative charge on more electronegative atom is more stable therefore as oxygen is very unstable, A is also stable

then check charge seperation. less charge seperation increases stability both C and D have same seperation but oxygen lone pairs will repel negative charge on carbon in D. therefore it becomes unstable. therefore D is the answer
