Question

The correct match between items of List – I and List – II is:
List I
List II
(A) Phenelzine
(B) chloroxylenol
(C) Uracil
(D) Ranitidine

List II
(P) Pyrimidine
(Q) Furan
(R)Hydrazine
(S) Phenol
A.(A) – (S); (B) – (R); (C) – (P); (D) – (Q)
B.(A) – (R); (B) – (S); (C) – (P); (D) – (Q)
C.(A) – (R); (B) – (S); (C) – (Q); (D) – (P)
D.(A) – (S); (B) – (R); (C) – (Q); (D) – (P)

Answer 1

Hint: In the list I we have been given the compounds and in the list II there are molecules that are contained in the compound in List I. we need to match them respectively. It is required to have knowledge about the structure of the given compounds to solve this question. In most cases, the suffix in the name can be used to match for some compounds like hydrazines, phenols etc.

Complete step by step answer:
Phenelzine is a non selective and irreversible MAOI that is a monoamine oxidase inhibitor of the hydrazine class. It is sold under the name of Nardil. Hence, Phenelzine matches with hydrazine.
Chloroxylenol is also known as para-chloro-meta xylenol, PCMX. It is available as liquid. It is not toxic to humans and birds but it causes moderate toxicity in water bodies. It is very toxic for fish and cats. It also causes some mild skin irritations. It contains a phenol unit in the formula. Hence (B) matches with (S).
Uracil, the IUPAC name for Uracil is pyrimidine-2, 4(1H,3H)-dione. Hence clearly it contains a unit of Pyrimidine. Hence (C) matches with (P).
Ranitidine contains a Furan ring in its molecular structure.

The correct option is B.

Note:
 Phenelzine is widely used clinically as an antidepressant and anxiolytic. It is taken orally. Chloroxylenol is used as a disinfectant and antiseptic. It is used for sanitation in hospitals. It is contained in household antiseptic drugs such as dettol, cream and ointments. Ranitidine is sold under the name Zantac. It is used to reduce the stomach acidity and in the treatment of peptic ulcers. It can be given by mouth or by injection into muscle or in vein. Uracil is one of the nucleobases in the RNA.
