correct order of resonance energy

Question

CH3COOH      CH3COONa    CH3CONH2

    1                        2                      3

Among these the correct order of  resonance energy  

A] 1>2>3                B]3>2>1              C] 2>3>1              D] 2>1>3

Answer 1

The  correct order to the arranging of resonance energy is C) 2 > 3 > 1

because resonance energy is more if a canonical structure is equivalent than if a canonical structure is non-equivalent
