What is the general molecular formula of the homologous series of alkane?

Open in App

Solution

The homologous series of alkane differs from only one $C H_{2}$ group in successive alkane compounds thus, they have a general molecular formula of $C_{n} H_{2 n + 2}$ .
Here n is the number of carbon atoms ( $C$ ) present in the compound.
Examples for homologous series of alkane are Methane $C H_{4}$ , Ethane ( $C_{2} H_{6}$ ) and etc.

What is the general molecular formula of the homologous series of alkane?

The homologous series of alkane differs from only one CH2 group in successive alkane compounds thus, they have a general molecular formula of CnH2n+2. Here n is the number of carbon atoms (C) present in the compound. Examples for homologous series of alkane are Methane CH4, Ethane (C2H6) and etc.
