What is a homologoues series.
List any four characteristics of
homologués series.
Answers
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:
A homologous series is a family of hydrocarbons with similar chemical properties who share the same general formula. We will look at three hydrocarbon series: alkanes, alkenes and the cycloalkanes. 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.
