Why ,benzene undergoes substitution reaction more readily than addition reaction ?

Answer»

SOLUTION :`(i)` Benzene CONTAINS delocalized `pi`-electrons which make the ring to ACT as an electro RICH centre. So electrophilic substiution reaction occurs in benzene.
`(ii)` Benzene ring is stabilized by delocalized `pi` electrons. Though it is highly stable, it undergoes ADDITION and oxidation reaction under specic conditions.
