Explanation:

Hexachlorocyclohexane (HCH), C

6H

6Cl

6, is any of several polyhalogenated organic compounds consisting of a six-carbon ring with one chlorine and one hydrogen attached to each carbon. This structure has nine stereoisomers (eight diastereomers, one of which has two enantiomers), which differ by the stereochemistry of the individual chlorine substituents on the cyclohexane. It is sometimes erroneously called "benzene hexachloride" (BHC). They have been used as models for analyzing the effects of different geometric positions of the large atoms with dipolar bonds on the stability of the cyclohexane conformation.[1] The isomers are poisonous, pesticidal, and persistent organic pollutants, to varying degrees.

Hexachlorocyclohexane was dimerized to produce mirex, a banned pesticide.

Common forms are:

alpha-hexachlorocyclohexane, α-HCH, or α-BHC (CAS RN: 319-84-6 ), the optically active isomer

beta-hexachlorocyclohexane, β-HCH, or β-BHC (CAS RN: 319-85-7 )

gamma-hexachlorocyclohexane, γ-HCH, γ-BHC, or lindane (CAS RN: 58-89-9 ), the most insecticidal isomer

delta-hexachlorocyclohexane, δ-HCH, or δ-BHC (CAS RN: 319-86-8 )

technical hexachlorocyclohexane, t-HCH, or t-BHC (CAS RN: 608-73-1 ), a mixture of isomer
