Why should resonance occur in benzene?

[ajaysabarish]

the carbon in benzene is sp2 hybridized and the p orbital is involved in double bond.sp2 orbitals and p orbitals are perpendicular to each other,for any electronic transition between orbitals,the orbitals should not be perpendicular.so how does pi electron go to carbon's orbital?

the p orbital is involved in double bond

There are no double bonds in benzene.

Google "aromaticity".

thank you for replying sir,but sir as far as i know,a pair of pi electrons get transferred to carbon orbitals the + and - charges form a bond.and it proceeds,iam asking how does the pi electron get transferred to carbon orbital,because the hybridized orbitals of carbon and pi orbital in which electrons are perpendicular.please reply
