Cyclohexadiene is an aromatic compound

Deactivating groups are ortho and para directing groups

Reaction of benzene with 1-chloro propane and anhydrous `AlCl_3` gives n propylbenzene

Electrophilic substitution of benzene takes place via `sigma`-complex

Hybrid orbitals do not form `sigma` bonds

Lateral overlap of p-orbitals or p-and d-orbitals produces `pi`-bonds

order`sigma_(p-p)ltsigma_(s-s)ltpi_(p-p)`

s-orbitals do not form o bonds
