Electron donating effect of - CH 3 group decreases electrophillicity of diazonium cation whereas electron with drawing effect of - NO 2 groups increases its electrophillicity increasing reactivity for diazocoupling. more reactive than (I) whare as (III), (V) (VI) are less reactive than (I).

Electron donating effect of −CH3​ group decreases electrophillicity of diazonium cation whereas electron with drawing effect of −NO2​ groups increases its electrophillicity increasing reactivity for diazocoupling. more reactive than (I) whare as (III), (V) & (VI) are less reactive than (I).
