Butan-1-ol and butan-2-ol are examples of
Correct answer: C. position isomers
- A. chain isomers
- B. functional group isomers
- C. position isomers
- D. geometric isomers
Explanation
The carbon skeleton and the functional group are the same in both, and only the position of the hydroxyl group along the chain differs, which defines position isomerism. Chain isomers differ in the branching of the skeleton, and functional group isomers carry different groups altogether, as an alcohol and an ether do. Position isomerism is why butan-1-ol oxidises to an aldehyde while butan-2-ol gives a ketone.

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.
