$\bf\large\underline\pink{Answer:-}$

It's not just Cyclohexene, but ALL Alkene molecules that decolourise when they react with Bromine water. Alkenes contain a C=C double bond and thus we call them "unsaturated hydrocarbons". Bromine (Br2) breaks this C=C double bond and attaches itself to the Alkene molecule, forming an Alkane

Answer:

Unsaturated hydrocarbon undergoes additional reaction. So, ot decolourises the bromine colour.

This reaction(bromine water test) is used to distinguish saturated compound from unsaturated one.
