Diethyl ether and n-butanol are:
Correct answer: B. Functional group isomers
- A. Position isomers
- B. Functional group isomers
- C. Chain isomers
- D. Tautomers
Explanation
Isomers are of two kinds: structural isomers and stereo-isomers. (We have to consider structural isomers only for this question because we have been given two different molecules, without their 3D structure) There are 5 types of structural isomerism. n-butanol and diethyl ether are functional group isomers because, as apparent, they have different function groups, ie, alcohol and ether group respectively. They have the same molecular formula and the same number of similar atoms. Therefore, option B is the correct answer.

About Isomerism
Isomerism occurs when compounds have the same molecular formula but different atom arrangements or spatial orientations. The content includes chain, position, functional, metameric and tautomeric isomerism, along with geometrical and optical isomerism, including cis-trans forms, E/Z notation, chirality and enantiomers.
