Concept:A molecule can contain multiple distinct functional groups that must be individually identified.
Solution:- Based on standard versions of this past paper question, Compound X is usually a benzene ring substituted with a \( \text{-CH(OH)CH}_3 \) group and a \( \text{-CH}_2\text{CN} \) group.
- 1) Aryl Ring: The central benzene ring acts as the core (aryl group).
- 2) Secondary Alcohol: The \( \text{-CH(OH)CH}_3 \) group features an \( \text{-OH} \) attached to a carbon bonded to two other carbons (the ring and the methyl). This is a secondary alcohol.
- 3) Nitrile: The \( \text{-CN} \) group is a nitrile.
- Hence, the correct combination is secondary alcohol, nitrile, and aryl ring.
Why other options are incorrect:It is not a primary alcohol because the \( \text{-OH} \) carbon is bonded to two carbons. It is not an amine (which would be \( \text{-NH}_2 \)). It is not a phenol because the \( \text{-OH} \) is not directly attached to the benzene ring.
Quality & Fidelity Assurance:
Every question on BeambePrep is rigorously curated against the official PMDC syllabus with zero filler, zero out-of-syllabus content, and zero typos. When an authentic past paper originally contained a historical mistake or ambiguity from the examining board (such as UHS or NUMS), BeambePrep faithfully reflects the original paper while detailing the nuance and scientific consensus in the autopsy above.
