Chemical name of Gammaxane is - (1) Toluene (2) Chloro benzene (3) Aniline (4) Benzene hexachloride

1 Answer

Answer :

(4) Benzene hexachloride Explanation: Gammexane is an insecticide that is the gamma isomer of benzene hexachloride. It is also known as lindane. Benzene hexachloride is any of several stereoisomers of 1,2,3,4,5,6- hexachlorocyclohexane formed by the lightinduced addition of chlorine to benzene.
