NEET 2026 (Phase 1) · ChemistryPrevious Year Question
The pair of molecules that are metamers among the following is:
Answer: (D) and . \textbf{Answer:} (d) \textbf{Solution:} Metamerism arises from different alkyl groups attached on either side of the same functional group (here, the ether oxygen).
- A. and
- B. and
- C. and
- D. and ✓
Correct Answer
(D) and
Solution & Explanation
\textbf{Answer:} (d) \textbf{Solution:} Metamerism arises from different alkyl groups attached on either side of the same functional group (here, the ether oxygen). (methyl propyl ether) and (diethyl ether) have the same molecular formula but different alkyl groups around oxygen, so they are metamers. Option (A) is functional/position isomerism (alcohols), (B) is chain isomerism (alkanes), and the esters in (C) are not metamers.
