Write the molecular formula of the 2^nd and 3^rd members of the homologous series where the first member is ethyne.

Academic Chemistry NCERT Class 10

The molecular formula of the 2nd and 3rd members of a homologous series where the first member is ethyne (C₂H₂) is formed by adding -CH₂-

2nd member = propyne (C₃H₄) CH₃ - CH₂ - C º CH

3rd member = butyne (C₄H₆) CH₃ - CH₂ - C º CH
