What is Bch full form ?

Benzene hexachloride (BHC),

any of various

stereoisomers of 1,2,3,4,5,6-hexachlorocyclohexane formed through the light-prompted addition of chlorine to benzene.

One of these isomers is an insecticide called lindane, or Gammexane.

Benzene hexachloride become first prepared in 1825; the insecticidal properties were identified in 1944 with the γ-isomer (gamma-isomer), which is about 1,000 instances more poisonous than any of the opposite diastereomers formed in the reaction. The structural variations among these individuals are within the orientations of the chlorine atoms with appreciate to the hoop of carbon atoms.

BHC full form

Details bch

The chemical addition of chlorine to benzene produces a mixture of numerous stereoisomers of 1,2,3,4,5,6-hexachlorocyclohexane. The γ-isomer, which makes up 20–25 percent of this mixture, is more soluble than the other isomers in certain solvents and can be separated from them. More risky than DDT, BHC has a faster however much less protracted movement upon insects.


Lindane has been shown to accumulate within the food chain. This happens due to the fact animals, together with humans, eat ingredients grown in lindane-contaminated soils, and fishes and different marine lifestyles are exposed to lindane-infected waters. In fishes and mammals, exposure to excessive degrees of lindane may also reason acute poisoning, that is evidenced with the aid of nervous device dysfunction. Chronic exposure may also adversely affect liver function in humans. Lindane’s use interior in smoke fumigators is not permitted, and its use as an insecticide has been banned in lots of countries. Topical use in creams to combat lice is permitted.
