Question

The correct stability order of the following resonance structures is $\underset{(I)}{H_{2}C=\stackrel{+}{N}=\stackrel{-}{N}}\underset{(II)}{H_2\stackrel{+}{C}-N=\stackrel{-}{N}}\underset{(III)}{H_2\stackrel{-}{C}-\stackrel{+}{N}=N}\underset{(IV)}{H_2\stackrel{-}{C}-N=\stackrel{+}{N}}$

• A. (I) > (II) > (IV) > (III)
• B. (I) > (III) > (II) > (IV)
• C. (II) > (I) > (III) > (IV)
• D. (III) > (I) > (IV) > (II)

Answer 1

Answer: (B)

On the basis of stability of resonating structures.
