General formula of the homologous series of alkanes is `C_(n)H_(2n+2)`. Write down the molecular formula of the `8^("th")` and `12^("th")` member using this.

Explanation

a. The general formula of the homologous series of alkanes is `C_(n)H_(2n+2)`.
b. The molecular formula of `8^("th")` member of the homologous series of alkanes `=C_(8)H_((2xx8+2))=C_(8)H_(18)`
c. The molecular formula of `12^("th")` member of the homologous series of alkanes `=C_(12)H_((2xx12+2))=C_(12)H_(26)`
