Question

Benzene hexachloride (BHC) is used by farmers for
(A) Making up mineral deficiency
(B) Killing harmful insects
(C) Removing salinity of the soil
(D) Making the soil rich in nitrogen

Answer 1

Hint: Benzene hexachloride (BHC) is a bug spray called lindane. Lindane is set up by treating chlorine with benzene within the sight of daylight and without oxygen just as replacement catalysts. These are harmful substances since it is toxic to all the living organisms.

Complete answer:
Benzene hexachloride (BHC) is otherwise called lindane, gamma-hexachlorocyclohexane, gammaxene and Gammallin. Lindane is an organochlorine compound and an isomer of hexachlorocyclohexane that has been utilized both as a farming bug spray and as a drug treatment for lice and scabies. Lindane is a neurotoxin that meddles with GABA synapse work by collaborating with the GABA-A receptor-chloride channel complex at the picrotoxin restricting site.

Hence the correct answer is OPTION(B)

Note: The World Health Organization groups lindane as the moderately toxic substance. The creation and horticultural utilization of lindane was restricted under the Stockholm Convention on steady natural pollutants. A particular exception to that boycott permits it to keep on being utilized as a second-line drug treatment for lice and scabies.
