1.	Why benzene undergoes electrophillic substitution reaction where as alpenses undergoes addition reaction?
Answer» SOLUTION :`(i)` BENZENE posses an in hybridised `p`- orbital containing one electron. The latral overlap of their `p`-ORBITALS produces `3pi`-bond `(ii)` The six-electron of the `p`-orbitals over all the six carbon atoms and are said to be delocated. `(iii)` Due to delocalisation strong `pi`-bond is formed which makes the molecule STABLE. `:.` benzene undergoes electrophilic substiution reaction.
