Show Hint
Molisch’s test is used to detect carbohydrates, Biuret test identifies peptides or proteins, Carbylamine test identifies primary amines, and Schiff’s test detects aldehydes
- (A) - III, (B) - IV, (C) - II, (D) - I
- (A) - II, (B) - I, (C) - III, (D) - IV
- (A) - III, (B) - IV, (C) - I, (D) - II
- (A) - I, (B) - II, (C) - III, (D) - IV
The Correct Option is B
Solution and Explanation
- Molisch’s Test: Used for the detection of carbohydrates. So, (A) – II.
- Biuret Test: Used for detecting peptide bonds, thus identifying proteins. So, (B) – I.
- Carbylamine Test: Used for detecting primary amines. So, (C) – III.
- Schiff’s Test: Used to detect aldehydes. So, (D) – IV.

Concepts Used:
Amines
Amine is a type of compound which is derived from ammonia (NH3). According to Organic chemistry, they are basically classified as the functional groups of the organic nitrogen compounds that contain nitrogen atoms with a lone pair.
Amine - Types
Primary Amines:
It is formed when one hydrogen atom in ammonia is substituted by an alkyl or aromatic group. Amino acids and methyl amine are the best examples that why aromatic amines include aniline.
Secondary Amines:
Amines that have two organic substitutes either alkyl or aryl ones or both and are bound to the nitrogen together with one hydrogen are termed as secondary amines. For Example, Dimethylamine.
Tertiary Amines:
Tertiary Amines are the amines where the nitrogen consists of three organic substitutes. For example, Trimethylamine and EDTA.
