Final answer:
The molecule C₆H₁₀ can have several alkyne isomers due to the possibility of different positions for the triple bond and branching of the carbon chain. Alkynes are unsaturated hydrocarbons with a general formula of CnH₂n-2. Geometric isomerism does not apply to alkynes as it does to alkenes.
Step-by-step explanation:
Number of Alkyne Isomers for C₆H₁₀
The molecule with the molecular formula C₆H₁₀ can have several structural isomers when considering the alkyne category, as alkynes are unsaturated hydrocarbons containing a triple bond. The general formula for alkynes with one triple bond is CnH₂n-2. With six carbon atoms, the structural possibilities for alkynes increase.
Isomers are compounds that have the same molecular formula but different structural formulas. They can significantly vary in structure, with the position of the triple bond being the most common source of diversity in alkynes. Considering a linear carbon chain as a base, the triple bond can be located in different positions, leading to various straight-chain alkynes. Additionally, the carbon chain can be branched, which further increases the number of possible isomers.
The ethyne molecule is a simple example of an alkyne, being linear with sp hybridization on each carbon atom. However, with a larger carbon chain like C₆H₁₀, the potential for branching and varying the position of the triple bond results in multiple isomers. Geometric isomerism does not apply to alkynes like it is to alkenes since triple bonds cannot exhibit cis-trans isomerism due to their linear nature.
