Solution

IUPAC name of DDT is 2, 2-bis (4-chlorophenyl)-l, 1, 1-trichloroethane.

IUPAC name of benzene hexachloride is 1, 2, 3, 4, 5, 6-hexachlorocyclohexane.

Their use is banned in India and other countries because they are highly toxic and are not biodegradable. Instead they are stored in the fatty tissues and their concentration keeps increasing in the food chain.
