Identify the correct statement in the following:

Options

A. Dimethyl ether and ethanol are chain isomers.
B. Ethanoic acid and methyl methanoate are position isomers.
C. n-butane and isobutane are functional isomers.
D. Propan-l-ol and propan-2-ol are position isomers.

Answer

D

Explanation

`underset("ether")("Functional isomers"): underset(underset("(alcohol)")("Dimethyl ether"))(CH_(3)-O-CH_(3)), underset("Ethanol")(CH_(3)CH_(2)OH)`
Functional isomers: `underset(underset("(Carboxylic acid)")("Ethanoic acid"))(CH_(3)COOH)`, `underset(underset("(ester)")("Methyl methanoate"))(H-overset(O)overset(||)C-OCH_(3))`
Chain isomers: `underset("n-Butane")(CH_(3)-CH_(2)-CH_(2)-CH_(3))`, `underset("Isobutane")(CH_(3)-underset(CH_(3))underset(|)(CH)-CH_(3))`
Position isomers: `underset("Propan-1-ol")(CH_(3)-CH_(2)-CH_(2)-OH)`, `underset("Propan-2-ol")(CH_(3)-underset(OH)underset(|)(CH)-CH_(3))`
