Question

Which of the following has a triple bond as well as single bonds?

Options

• ethene

• methane

• ethyne

• nitrogen

Answer 1

Ethyne

Explanation:

Ethyne (C₂H₂) consists of two carbon atoms connected to each other by a central covalent triple bond (C ≡ C). Additionally, each carbon atom is connected to a hydrogen atom via a single covalent bond (C-H). Therefore, the entire molecule simultaneously contains one triple bond and two single bonds to satisfy the valency requirements of all atoms.
