Question

Choose the correct options regarding homologous series-

• A. As the size of carbon chain in any homologous series increases, a gradation in physical properties is seen.
• B. Melting and boiling point increase with molecular mass.
• C. Chemical properties remain similar in a homologous series.
• D. All of the above.

Answer 1

The correct option is D All of the above.

With an increase in the size of carbon chain in a homologous series, a gradation of physical properties occurs. The boiling point is a physical property and it increases with increase in the size of the carbon chain.
Melting and boiling points are physical properties. The melting and boiling point increases with increase in the size of a carbon chain.
Since the functional group does not change in a homologous series, the chemical properties remain almost same.
