Question

Given below are the structure of few compounds with molecular formula $C_{4}H_{10}O$ . Select metamers from these structure.

(i) $CH_{3}-O-CH_{2}CH_{2}CH_{3}$

(ii) $CH_{3}CH_{2}CH_{2}CH_{2}OH$

(iii) $CH_{3}-CH_{2}-O-CH_{2}-CH_{3}$

(iv) $CH_{3}-\underset{O H}{\underset{\left|\right.}{C} H}-CH_{2}-CH_{3}$

• A. (i) and (ii)
• B. (ii) and (iii)
• C. (i) and (iii)
• D. (ii) and (iv)

Answer 1

Answer: (C)

$CH_{3}-O-CH_{2}CH_{2}CH_{3}$ and $CH_{3}-CH_{2}-O-CH_{2}-CH_{3}$ are metamers.

(ii) and (iv) i.e. $CH_{3}CH_{2}CH_{2}CH_{2}OH$ and $CH_{3}-\underset{O H}{\underset{\left|\right.}{C} H}-CH_{2}-CH_{3}$ are position isomers.
