Answer 2

First, four members of the homologous series of aldehydes are -

1. A homologous series contain carbon compounds that differ in the number of carbon atoms but the functional group is the same.

2. They are a part of organic chemistry.

3. The chemical characteristics are exhibited in these compounds for they belong to the same functional groups.

4. The  Ch2 group differs in the molecules. As the molecular weight keeps on increasing, features like melting points also change accordingly.

5. First, four members of the homologous series of aldehydes are - methanal, ethanal, propanal, and butanal.
