Question

The general formula of alkynes is_________.

Answer 1

Alkynes

• Alkynes are unsaturated hydrocarbons.
• They contain at least one triple bond between two carbon atoms.

The general formula of alkynes

• The general formula of alkynes is ${\text{C}}_{\text{n}}{\text{H}}_{\text{2n–2}}$.
• Here, n is the number of carbon atoms in the molecule.
• For example, ethyne contains two carbon atoms. So, the formula of ethyne is ${\text{C}}_{\text{2}}{\text{H}}_{\text{2}}$.

Hence, the general formula of alkynes is ${\text{C}}_{\text{n}}{\text{H}}_{\text{2n–2}}$.
