Vedclass · Answer

(C) $1$. The starting material is $1,3,5$-trimethylbenzene (mesitylene). $2$. Electrophilic aromatic substitution with $Br_2$ in $CCl_4$ occurs at the position ortho to the methyl groups. Since all positions are equivalent, it forms $2$-bromo-$1,3,5$-trimethylbenzene $(A)$. $3$. Treatment of $A$ with $Mg$ in dry ether forms the Grignard reagent, $2,4,6$-trimethylphenylmagnesium bromide. $4$. Reaction of the Grignard reagent with dry ice $(CO_2)$ followed by acidic workup $(H_3O^+)$ yields the corresponding carboxylic acid, $2,4,6$-trimethylbenzoic acid $(B)$.

The compounds $A$ and $B$ are respectively
