Which of the following compounds can be detected by Molisch's test ?

A
Nitro compounds
Correct answer
B
Sugars
C
Amines
D
Primary alcohols

Solution

Molisch's Test : when a drop or two of alcoholic solution of $\alpha$-naphthol is added to sugar solution and then conc. $\mathrm{H}_2 \mathrm{SO}_4$ is added along the sides of test tube, formation of violet ring takes place at the junction of two liquids.

Hence, the correct answer is option: 'B'.
