Which of the following will be the most stable diazonium salt `(RN_(2)^(+) X^(-))` ?

Options

A. `CH_3N_2^(+)X^(-)`
B. `C_6H_5N_2^(+) X^(-)`
C. `CH_3CH_2N_2^+X^(-)`
D. `C_6H_5CH_2N_2^+X^(-)`

Answer

B

Explanation

Out of the given diazonium slts , `C_6H_5N_2^(+)X^(-)` is resonance stabilised hence most stable.
