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:
Acetic acid, oxalic acid and formic acid in the increasing order of their acidity.
b) p-Bromobenzoic acid, p-nitrobenzoic acid, 2,4-dinitrobenzoic acid
Interpretation:
p-Bromobenzoic acid, p-nitrobenzoic acid and 2,4-dinitrobenzoic 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 functional group.
To arrange:
p-Bromobenzoic acid, p-nitrobenzoic acid and 2,4-dinitrobenzoic acid are to be arranged in the increasing order of their acidity.
c) Fluoroacetic acid, 3-fluoropropanoic acid, iodoacetic acid
Interpretation:
Fluoroacetic acid, 3-fluoropropanoic acid and iodoacetic 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 functional group.
