Question

Give an example of isomers shown by triple bond hydrocarbons (alkynes) and write their IUPAC names.

Answer 1

Position isomerism is a common observation in triple bond hydrocarbons (alkynes). This means the position of the triple bond changes within the carbon chain, even though the molecular formula remains the same.

Example of isomers in Alkynes:

Let’s consider the molecular formula C₄H₆. This molecule corresponds to butyne (an alkyne with 4 carbon atoms and a triple bond).

\[\ce{\underset{But-1-yne}{CH3 - CH2 - C ≡ CH}}\]

\[\ce{\underset{But-2-yne}{CH3 - C ≡ C - CH3}}\]
