(pls explain)

Open in App

Solution

First two members of homologous series having functional group - Cl are :-
1. CH₃Cl - Chloromethane
2. C₂H₅Cl - Chloroethane
These series have a difference of -CH₂- unit

In organic chemistry, a homologous series is a series of compounds with the same general formula usually varying by a single parameter.This can be the length of a carbon atom.The homologous series of straight-chained alkanes begins methane (CH₄), ethane(C₂H₆), propane(C₃H₈), butane (C₄H₁₀).
