The typical reaction of benzene and other aromatic compounds are electrophilic substitution. Presence of electron donating group activates the ring towards electrophilic substitution, while presence of electron withdrawing group deactivates the ring towards electrophilic substitution but at the same time activates the ring towards nucleophilic substitution. Some groups are predominantly meta-directing and all of these are deactivating. Except halogen, most of the O– and P– directing groups are activating groups.
Which of the following compound is not formed.
X represents mixture of organic compounds. The mixture does not contain.

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 Meta-directing group is meta to an ortho-para directing group, the incoming group primarily goes ortho to the meta directing group rather than para.
