Question

The correct order of acidity of the following compounds is (A) 1>2>3 (B) 1>3>2 (C) 3>1>2 (D) 3>2>1

Tardigrade Admin · Accepted Answer

Electron donating substituents tends to decrease the acidic strength while electron withdrawing substituents tends to increase the acidic strength of substituted benzoic acids relative to benzoic acid. OCH 3 exerts +M effect which destabilises the conjugate base

of the compound 2 and hence decreases the acidity, whereas NO 2 exerts -M effect and stabilises the conjugate

hence increases the acidity. Thus, the correct order of acidity of the given compounds are
