Question

what is a homologous series of carbon compounds? list its any two characteristics .write the name and formula of next higher homologous of HCOOH.

Answer 1

homologous series is a group of organic compounds having same general formula shows a difference of CH2 having same chemical properties but different physical properties
C2H3=O

Answer 2

A homologous series is a series of compounds with the same functional group and similar chemical properties in which each succesive member differs by CH2.

Two characteristics are-

1. All the members of a homologous series can be represented by the same general formula.

2. The difference in the molecular masses of any two adjacent homologous series is 14 units.

The name and formula of next higher homologue of HCOOH is ethanoic acid, CH3COOH
