Question

Match the following drugs with correct functional group test

List (i)	List(ii)
A) Chloroxylenol	P) Carbylamines
B) Penicillin	Q) Baeyer’s reagent
C) Sulpha Pyridine	R) FeCl3 test
D) Norethindrone	S) Sodium hydrogen sulphate

• A. A → R, B → P, C → S, D → Q
• B. A → S, B → R, C → P, D → Q
• C. A → R, B → S, C → P, D → Q
• D. A → Q, B → R, C → P, D → S

Answer 1

The correct option is C

A → R, B → S, C → P, D → Q

Explanation with diagram for the correct answer:

(C)A → R, B → S, C → P, D → Q

(A)Chloroxylenol-(R)FeCl₃ test

Chloroxylenol contains an OH group it is responding to the neutral FeCl₃ test.

Diagram:

(B) Penicillin-(S) Sodium hydrogen sulphate

Penicillin contains a COOH group it is responding to the sodium hydrogen sulphate test.

Diagram:

(C)Sulpha Pyridine-(P)Carbylamines

Sulpha pyridine NH₂ group it is responding to the carbylamines test.

Diagram:

(D) Norethindrone-(Q)Baeyer’s reagent

Norethindrone C ≡ CH – it is responding to the Bayers test

Diagram:

Therefore, option (C) is correct.
