Question

What is homologous series give its features

Answer 1

A series of molecules in which the molecular diff. between 2 consecutive molecules is -CH2- and mass diff. is 14 u.
Features:
Mass diff. -14u
Molecular diff . -CH2-
General process of preparation
Molecules of any homologous series have a general formula

Answer 2

HOMOLOGOUS SERIES ;- A series of compounds in which the same functional group subsitutes for hydrogen in a carbon chain is called a HOMOLOGOUS SERIES.
