Question: Which of the following will be most stable diazonium salt $R \mathrm{~N}_2{ }^{+} X^{-}$?#

A) $\mathrm{CH}_3 \mathrm{~N}_2{ }^{+} X^{-}$

B) $\mathrm{C}_6 \mathrm{H}_5 \mathrm{~N}_2{ }^{+} X^{-}$

C) $\mathrm{CH}_3 \mathrm{CH}_2 \mathrm{~N}_2^{+} X^{-}$

D) $\mathrm{C}_6 \mathrm{H}_5 \mathrm{CH}_2 \mathrm{~N}_2^{+} X^{-}$

Answer: $\mathrm{C}_6 \mathrm{H}_5 \mathrm{~N}_2{ }^{+} X^{-}$#

Sol:#

Aromatic diazonium salts are more stable due to dispersal of the positive charge in benzene ring.
