Question

Write the molecular formula of the first two members of the homologous series having functional group – Br(bromine)

Answer 1

CH3Br, C2H5Br is the answer for your question

Answer 2

Explanation:

A series which contains same group of chemicals which almost have similar chemical properties and have a certain general formula is known as a homologous series.

For example, $CH_{3}Br$ and $C_{2}H_{5}Br$ is a homologous series that contains bromine as its functional group.

Therefore, we can conclude that the molecular formula of the first two members of the homologous series having functional group – Br(bromine) is $CH_{3}Br$ and $C_{2}H_{5}Br$.
