Cyclohexane

Vedclass · Answer

(A) Bromine water is decolourised by compounds that undergo addition reactions with bromine,such as alkenes,or by compounds that undergo electrophilic substitution,such as phenol and aniline.$(1)$ Phenol reacts with bromine water to form $2,4,6$-tribromophenol,which is a white precipitate,thus decolourising the bromine water.$(2)$ Styrene contains a carbon-carbon double bond,which undergoes an addition reaction with bromine water,leading to decolourisation.$(3)$ Aniline reacts with bromine water to form $2,4,6$-tribromoaniline,which is a white precipitate,thus decolourising the bromine water.$(4)$ Cyclohexane is a saturated hydrocarbon and does not react with bromine water under normal conditions,so it does not decolourise it.Therefore,cyclohexane does not decolourise bromine water.

Which one of the following compounds does not decolourize bromine water?
