Question
What do you mean by homologous series and homologues?
Answer
A homologous series is a group of organic compounds that have similar chemical properties, share a general formula, and differ by a constant increment in their molecular structure.
Homologues are compounds that belong to the same homologous series and have the same functional group, but differ in the number of carbon atoms in their molecule. They have similar chemical properties, but their physical properties (such as melting and boiling points) increase as the molecular size increases.
