Question

what is homologous series? write any four property of homologous series​

Answer 1

In organic chemistry, 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.

Four characteristics of a homologous series are: (i) The general formula of all compounds in the series is the same. (ii) They have the same functional group. (iii) Their physical properties such as melting point, boiling point, density, generally show a gradual change with increase of molecular formula in the series.

Answer 2

$\colorbox{plum}{Homologous \: series}$

A group of organic compounds which can be represented by the same general formula with a same functional group

Characteristics :

⭐The members of the homologous series have same functional group.

⭐Members have the same general formula.

⭐Members have the almost same chemical properties due to same functional group.

⭐Members have common general method of preparation.
