Question

Define Isomerism and Homologous seris​

Answer 1

Answer:

Isomerism seris

Isomerism, the existence of molecules that have the same numbers of the same kinds of atoms but differ in chemical and physical properties.  Such structures also would be analogous to isomers. In a more subtle analogy, one's hands can be seen as isomeric.

Homologous seris​

a homologous series is a sequence of compounds with the same functional group and similar chemical properties in which the members of the series can be branched or unbranched, or differ by -CH2
