Question

How will you prepare the following compounds from benzene? You may use any inorganic reagent and any organic reagent having not more than one carbon atom: p-Nitrobenzaldehyde.

Answer 1

This reaction will give us CH3 benzene in the presence of CH3Cl.

Then when it is taken under the HNO3/H2SO4 then we will get Benzene wit CH2 and NO2.

Take it with CS2 and CrO2Cl2 then we get, a Benzene ring with NO2 and CH(OCrOHCl2)2.

Hydrolase it at the end to obtain p- Nitrobenzaldehyde.
