NEET 2026, Chemistry Q12: Carboxylic Acid Derivatives

NEET2026Chemistry

In a test tube containing a salt, a few drops of dilute H $_{2}$ SO $_{4}$ was added, which gave colourless vapours having the smell of vinegar. The vapours turned the blue litmus paper red. Identify the correct anion from the following :

A
Carbonate, $C O_{3}^{2 -}$
B
Sulphide, $S^{2 -}$
C
Acetate, $C H_{3} C O O^{-}$
D
Sulphate, $S O_{4}^{2 -}$

Solution

Acetate salts on treatment with dilute H $_{2}$ SO $_{4}$ release acetic acid (CH $_{3}$ COOH), which has the characteristic vinegar smell and turns blue litmus red.
