Which pair is correctly matched?

Options

A. n-butane and isobutane, metamers
B. 2-pentanol and 3-pentanol, position isomers
C. Cyclohexene and cyclopentene, chain isomers.
D. methyl propyl ether and diethyl ether, functional isomers

Answer

B

Explanation

n-butane and Isobutane are chain isomers 2 pentanol 3-pentanol are position isomers cyclohexene and cyclopentene are not isomers methyl propyl ether and diethyl ether are Metamers.
