$3-$Nitrobenzaldehyde

Vedclass · Answer

(D) The reaction sequence is as follows:$1$. The first step is the Etard reaction,where toluene is oxidized to benzaldehyde using chromyl chloride $(CrO_2Cl_2)$ in the presence of carbon disulfide $(CS_2)$,followed by hydrolysis with $H_3O^+$.$2$. The second step is the nitration of benzaldehyde using a nitrating mixture $(HNO_3/H_2SO_4)$.$3$. The $-CHO$ group is a meta-directing group,so the nitro group $(-NO_2)$ will be introduced at the meta-position relative to the aldehyde group.$4$. Thus,the final product $X$ is $3$-nitrobenzaldehyde.

What is $X$ in the following reaction sequence?
$Toluene \xrightarrow[ii. HNO_3/H_2SO_4]{i. CrO_2Cl_2/CS_2, H_3O^+} X$
