Write the molecular formulae of the third and fifth members of homologous series represented by the general formula CnH2n−2.
Open in App
Solution
The general formula for unsaturated hydrocarbon alkyne is CnH2n−2, where n is the number of carbon atoms in one molecule of the alkyne.
For the third and fifth members of homologous series of alkyne family, n = 4 and n = 6 respectively. The corresponding molecular formulae will be:
n
General Formula
CnH2n−2
Molecular Formula
4
C2H2(4)−2
C4H6
6
C2H2(6)−2
C6H10
