Question

Why does benzene not decolourize bromine water?

Answer 1

Answer:

Explanation:

Benzene molecule is unsaturated but it does not undergo electrophillic addition reaction because saturating the carbon-carbon bonds destroys the delocalized pi-cloud and as we know that this delocalized pi-structure is very stable. So due to this benzene does not decolourises bromine water.

Answer 2

Answer:

However, the “double bonds” in benzene are delocalised and not stationary. Their delocalisation stabilises the molecule and protects the usually reactive double bond from any addition reaction of sorts- the bromine water in this case
