Question

A pair of homologous series of organic compound having double bond is *
1 point
C₂H₆, C₃H₈
C₂H₂, C₃H₄
C₃H₆, C₅H₁₀
C₃H₆ , C₄H₄​

Answer 1

Answer:

A series of organic compounds each containing a characteristic functional group and the successive members differ from each other in the molecular formula by −CH

2

− group is called homologous series.

In homologous series, homologues are arranged in the increasing order of their molecular mass.

Characteristics of homologous series :

Homologues can be represented by same general formula and functional group.

They can be prepared by the same chemical methods.

They show similar chemical properties, and gradation in physical properties such as melting point, boiling point, density, solubility, etc.

Here, C

differ by −CH

2

− group, hence they belong to same homologous series.
