A third group is least likely to enter between two groups in the meta relationship. This is the result of steric hindrance and increases in importance with the size of the groups on the ring and with the size of the attacking species. When a Meat-directing group is meta to an ortho-para directing group, the incoming group primarily goes ortho th the meta directing group rather than para. Chlorination of m- chloro nitro benzene gives :

Ortho effect is special type of effect that is shown by o-subsituents .This ortho-effect operates at the benzoic acids irrespective of the polar type. Nearly all o-substituted benzoic acid are stronger than benzoic acid. Benzoic acid is a resonance stabilised and so the carboxyl group is coplaner with the ring. An o-subsituent tends to prevent this coplanarity. Which among the following will be the strongest acid ?
