2-propanol and 1-propanol show the isomerism________________?
Correct answer: D. position isomerism
- A. metamerism
- B. functional group isomerism
- C. geometric isomerism
- D. position isomerism
Explanation
1-propanol and 2-propanol have the same molecular formula and the same alcohol functional group, but the OH group is attached at different positions on the carbon chain. This is position isomerism; students may choose functional group isomerism by noticing only that the compounds are different alcohols.

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.
