a) Acetic acid, oxalic acid, formic acid
Interpretation:
Acetic acid, oxalic acid and formic acid are to be arranged in the increasing order of their acidity.
Concept introduction:
Any electron withdrawing group present in the acid increases the acidity of the acid while any electron releasing group present in the acid decreases the acidity. Inductive effect decreases with increasing distance of the substituent from the
To arrange:
