Vedclass · Answer

(A) The electron-donating or withdrawing nature of these groups is determined by their resonance and inductive effects.$1$. $-NH_2$ has a strong $+M$ effect (electron-donating).$2$. $-OCH_3$ has a $+M$ effect,but it is weaker than $-NH_2$ due to the higher electronegativity of oxygen.$3$. $-C_6H_5$ (phenyl group) has a weak $+M$ effect or can act as an electron-withdrawing group depending on the system.$4$. $-NO_2$ has a strong $-M$ and $-I$ effect (electron-withdrawing).Thus,the order of electron-donating ability is $-NH_2 > -OCH_3 > -C_6H_5 > -NO_2$.

The correct order of the electron-donating or withdrawing effect (inductive/mesomeric effect) for the groups $-NH_2, -OCH_3, -C_6H_5$,and $-NO_2$ is:
