Chemistry - Aromatic Hydrocarbon Question with Solution | TestHub

Explain Question:

The question asks to match Column I with Column II.

Concept:

Electrophilic Aromatic Substitution (EAS) is a reaction in which an electrophile replaces a hydrogen atom on an aromatic ring, while the aromaticity of the ring is preserved. Liebermann’s Nitroso Test is a chemical test for phenols (especially resorcinol, hydroquinone, and catechol) and some aromatic amines. Phenols or certain aromatic amines react with alkaline nitrous acid ($NaN{O}_2+NaOH$) to form colored nitroso derivatives. The appearance of a blue or violet color indicates a positive test.

Solution:

(A) → P, S [Phenolphthalein formation]

(B) → P, T [Bakelite formation]

(C) → P, Q

(D) → P, R [Trinitrotoluene (T.N.T.) is formed]

Final Answer: (C)
