H - C ≡ C - CH₂ - CH₃ this is an alkyne molecule.
Hence, Option C is correct answer.
What is Alkane ?
The saturated hydrocarbon which have only single bonds between the carbon atoms is called Alkanes.
What is Alkene ?
The unsaturated hydrocarbon which have at least one carbon carbon double bond is called Alkene.
What is Alkynes ?
The unsaturated hydrocarbon which have one or more than one carbon carbon triple bonds is called Alkynes.
H - C ≡ C - CH₂ - CH₃ in this molecule one triple bond is present so it is alkyne.
Thus from the above conclusion we can say that H - C ≡ C - CH₂ - CH₃ this is an alkyne molecule.
Hence, Option C is correct answer.
