$1-$methyl$-2,4-$dinitrobenzene

Vedclass · Answer

(B) The starting material is $p$-nitrotoluene. The $-CH_3$ group is ortho/para directing,while the $-NO_2$ group is meta directing. In $p$-nitrotoluene,the para position is already occupied by the $-NO_2$ group. Therefore,the incoming electrophile $(NO_2^+)$ from the nitration reaction will be directed to the ortho position with respect to the $-CH_3$ group. This position is also meta to the existing $-NO_2$ group,which further supports the substitution at this site. Thus,the product $A$ is $2,4$-dinitrotoluene (or $1$-methyl-$2,4$-dinitrobenzene).

What will be the product $A$ in the reaction given below?
