WebFormic acid is stronger acid than acetic acid because of absence of +I group methyl in acetic acid. This means that K a of formic acid is greater than that of acetic acid and this implies that pK a of formic acid will be greater than that of formic acid. So, both assertion and reasons are incorrect. Hence, Option "D" is the correct answer. WebIn acetic acid, due to the +I effect of the alkyl group the electron density on the oxygen atom increases. The release of H + ion becomes difficult. Thus , greater the magnitude of +I effect weaker will be the acid. Order of +I effect : CH 3>H Therefore , formic acid (HCOOH) is more acidic than acetic acid (CH 3COOH).
