Question

what is homologous series

Answer 1

In chemistry, a homologous series is a group of compounds that share the same basic chemical makeup, but differ in the number of iterations of a certain aspect of their structure. Homologous series are referenced frequently in organic chemistry, where compounds can differ by the length of their carbon chain. These differences can have an effect on the physical properties of the chemicals, such as boiling point.
