How will you convert benzene into:
$I$. $p$-nitrotoluene
$II$. acetophenone

(N/A) $I$. Friedel-Crafts alkylation of benzene with methyl chloride $(CH_3Cl)$ in the presence of anhydrous aluminium chloride $(AlCl_3)$ gives toluene. Nitration of toluene with a mixture of conc. nitric acid $(HNO_3)$ and conc. sulphuric acid $(H_2SO_4)$ gives a mixture of ortho and para nitrotoluene,which are separated by fractional distillation.
$II$. Friedel-Crafts acylation of benzene with acetyl chloride $(CH_3COCl)$ in the presence of anhydrous aluminium chloride $(AlCl_3)$ gives acetophenone.
