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

Options

A. `C_(6)H_(5)CH_(2)N_(2)^(+)X^(-)`
B. `CH_(3)N_(2)^(+)X^(-)`
C. `CH_(3)CH_(2)N_(2)^(+)X^(-)`
D. `C_(6)H_(5)N_(2)^(+)X^(-)`

Answer

d

Explanation

C`C_(6)H_(5)CH_(2)N_(2)^(+)X^(-) , CH_(3)N_(2)^(+)` and `CH_(3)CH_(2)N_(2)^(+)X^(-)` are primary amine daizonium salts which are readlily decomposed and liberate `N_(2)` gas but `C_(6)H_(5)N_(2)^(+)X^(-)` is an aryl diazonium salt which is stabilised by resonance of benzene ring which is directly attached with nitrogen
