Question

Write the homologous series for alkynes.

Answer 1

Homologous series: Homologous series is a series of compounds having the same functional group and same chemical properties but the successive members of this series differ by $-{\mathrm{CH}}_2$ group.

Alkynes: Alkynes are those unsaturated hydrocarbons that have at least one triple bond between two carbon atoms.

• The homologous series of alkynes has a general formula ${\mathrm{C}}_{\mathrm{n}}{\mathrm{H}}_{2\mathrm{n}-2}$ Where, $\mathrm{n}$ is an integer greater than one.
• The first member of the alkyne homologous series is ethyne.
• The next members are propyne, butyne, and pentyne.
