calculation of pure and hybrid orbitals ratio of benzene
Dear student,
In Benzene each carbon is sp2 hybridizes. 2s and 2p orbitals of carbon participate in hybridization to form 3 sp2 hybrid orbitals but its 1s orbital remain unhybridized.
Hydrogen has only one 1s orbital and the single orbital can not undergo hybridization, so it remains in pure form.
thus there are 18 hybridized orbitals(3 from each carbon) and 12 pure orbitals( 1 from each carbon and 1 from each hydrogen) in a benzene ring.
Hence the ratio of pure and hybridized orbitals is 3:2.
