Solution

The general formula of a group of organic compounds is $C_{n} H_{2 n + 1} O H$
The molecular formula of first two members of this group are $C H_{3} O H$ and $C_{2} H_{5} O H$ . These are methanol and ethanol respectively. These two compounds are in homologous series, as they have same general formula, same functional group and differ from one another by methylene group.
