Vedclass · Answer

(A) $1$. Toluene reacts with $Br_2$ in the presence of $Fe$ (dark) via electrophilic aromatic substitution to form a mixture of $o$-bromotoluene $(P)$ and $p$-bromotoluene $(Q)$.$2$. These isomers react with $Mg$ in dry ether to form the corresponding Grignard reagents: $o$-tolylmagnesium bromide and $p$-tolylmagnesium bromide.$3$. These Grignard reagents react with formaldehyde $(HCHO)$ followed by acidic hydrolysis $(H_2O)$ to form primary alcohols.$4$. The final products $R$ and $S$ are $o$-methylbenzyl alcohol and $p$-methylbenzyl alcohol,respectively.

The possible final products $R$ and $S$ of the following reaction sequence are:
