Question 7
1 / -0

Which of the following will be most stable diazonium salt $$RN_2^{+}X^{-}$$ ?

A
$$CH_3N_2^{+}X^{-}$$

B
$$C_6H_5N_2^{+}X^{-}$$

C
$$CH_3 CH_2 N_2^{+}X^{-}$$

D
$$C_6H_5 CH_2 N_2^{+}X^{-}$$

Solution

Diazonium salt containing aryl group directly linked to the nitrogen atom is most stable due to resonance stabilisation between the benzene nucleus and N-atom.
