Which of the following isomerism is shown by alkynes?
Correct answer: A. Positional isomerism
- A. Positional isomerism
- B. Geometrical isomerism
- C. Cis-trans isomerism
- D. Functional group isomerism
Explanation
Alkynes can exhibit positional isomerism where the position of the triple bond changes within the carbon chain. For example, in the case of C4H6, you can have 1-butyne and 2-butyne, which are positional isomers.

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.
