(a) Give the names and structural formulae of the next two higher homologues of methane.(b) The molecular formula of a hydrocarbon is C₁₀H₁₈. Name its homologous series.
(c) Select the hydrocarbons which are members of the same homologous series. Give the name of each series.
C₅H₁₀ ; C₃H₈ ; C₆H₁₀ ; C₄H₁₀ ; C₇H₁₂ ; C₈H₁₆.

The next two higher homologues of methane are ethane and propane.

Ethane

(b) The molecular formula of a hydrocarbon is C10H18. Its homologous series is Alkyne (C_nH_2n-2).

(c) The hydrocarbons which are members of the same homologous series are:

Alkanes: C₃H₈, C₄H₁₀

Alkenes: C₅H₁₀, C₈H₁₆

Alkynes: C₆H₁₀, C₇H₁₂
