Vedclass · Answer

(A) To determine the acidity,we consider the electronic effects (inductive,resonance,and ortho effect) of the substituents on the benzoic acid ring.$(P)$ Pair: $2$-methylbenzoic acid vs $3$-methylbenzoic acid. Due to the ortho effect,$2$-methylbenzoic acid is more acidic than $3$-methylbenzoic acid.$(Q)$ Pair: $2$-nitrobenzoic acid vs $3$-nitrobenzoic acid. Due to the ortho effect,$2$-nitrobenzoic acid is more acidic than $3$-nitrobenzoic acid.$(R)$ Pair: $3$-methoxybenzoic acid vs $4$-methoxybenzoic acid. In $3$-methoxybenzoic acid,the $-OCH_3$ group exerts a $-I$ effect,which increases acidity. In $4$-methoxybenzoic acid,the $-OCH_3$ group exerts a strong $+M$ effect,which decreases acidity. Thus,$3$-methoxybenzoic acid is more acidic.Therefore,the set of more acidic compounds is $2$-methylbenzoic acid,$2$-nitrobenzoic acid,and $3$-methoxybenzoic acid.

The set representing the more acidic compound among each of the following $3$ pairs is:
