Question

what happens when benzene under go addition reaction​

Answer 1

Answer:

Benzene reacts with chlorine or bromine in the presence of a catalyst, replacing one of the hydrogen atoms on the ring by a chlorine or bromine atom. The reactions happen at room temperature. The catalyst is either aluminium chloride (or aluminium bromide if you are reacting benzene with bromine) or iron.

Answer 2

Answer:

Benzene doesn'tundergo addition reactions,because of its aromaticity which gives the benzene ring enough stability. if addition reaction takes place on benzene ring it lost its aromaticity. Because benzene is stablein its own and can not loose hydrogen.
