Question

Select from the following a hydrocarbon having one C-C bond and one C≡C bond:

Options

• Benzene

• Cyclohexane

• Butyne

• Propyne

Answer 1

Propyne

Explanation:

Propyne (CH≡C-CH₃) is a hydrocarbon characterized by the presence of one single carbon-carbon bond and one triple carbon-carbon bond. In contrast, Benzene consists of alternating double bonds (C=C) within a cyclic structure, Cyclohexane is a saturated cyclic compound featuring only single C-C bonds, and Butyne contains two single C-C bonds along with one triple bond (C≡C).
