Benzene reacts with chlorine in sunlight to give a final product.

Give the reaction for the acylation of benzene and its mechanism.

$CH_3-CH_2-CH_2-Cl$ $\xrightarrow{Na, \text{Dry ether}} P$ $\xrightarrow[V_2O_5, Al_2O_3]{\Delta} Q$. $Q$ is

Acylation process is preferred over direct alkylation in the Friedel-Crafts reaction because:

What is the product obtained when $n$-hexane is passed over a heated catalyst (chromium oxide supported on alumina) at $750 \ K$?

The Birch reduction of benzoic acid gives:
