Alkynes Isomers for Compound with Molecular Formula C₆H₁₀

Alkynes are hydrocarbons with at least one triple bond, following the general formula CnH2n-2, where n is the number of carbon atoms. Isomers are compounds with the same molecular formula but different structures.

The question is asking about the number of isomers of alkynes that exist for the molecular formula C₆H₁₀. When discussing alkynes, we're dealing with hydrocarbons that contain at least one carbon-carbon triple bond. According to the general formula for alkynes, which is CnH₂n-2, a compound with six carbon atoms would have (2n - 2) hydrogen atoms, and therefore the formula C₆H₁₀ aligns with an alkyne structure. Isomers are compounds that have the same molecular formula but different structural configurations.

For example, one possible structure is 1-hexyne where the triple bond is located at the end of the carbon chain. Another isomer could be 2-hexyne, where the triple bond has moved one carbon in. The position of the triple bond along the carbon chain and whether branches occur (as in the case of methyl or ethyl groups) are what give rise to different isomers. However, due to the nature of the question, one would need to draw out each possibility to determine the exact number of isomers, which has been provided as 11.
