Write the molecular formula of first two members of homologous series having function group – Cl.
Answer
Homologous series is a group/sequence of compounds which have the same functional group and similar chemical properties .
The two successive compounds differ by a CH 2 group.
Therefore, the first two members of homologous series having function group -Cl would be:
CH 3 Cl, CH 3 CH 2 Cl
