$-OCH_3$

Vedclass · Answer

(D) Key Idea: Functional groups that are electron-withdrawing due to resonance (often containing a double bond to a more electronegative atom) are meta-directing. Groups that donate electrons via resonance (due to the presence of lone pairs on the atom directly attached to the benzene ring) are ortho/para-directing.$(A)$ $-COOH$: The carbon atom attached to the benzene ring is bonded to an oxygen atom via a double bond. It is electron-withdrawing and thus meta-directing.$(B)$ $-NO_2$: The nitrogen atom attached to the benzene ring is bonded to an oxygen atom via a double bond. It is electron-withdrawing and thus meta-directing.$(C)$ $-CHO$: The carbon atom attached to the benzene ring is bonded to an oxygen atom via a double bond. It is electron-withdrawing and thus meta-directing.$(D)$ $-OCH_3$: The oxygen atom attached to the benzene ring has lone pairs of electrons,which it donates to the ring via resonance ($+M$ effect). Therefore,it is ortho/para-directing,not meta-directing.Thus,option $(D)$ is the correct answer.

Which one of the following functional groups is not meta directing?
