Question

Complete the chain
C₂H6, C4H8, C5H10​

Answer 1

Explanation:

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, C3H6, C4H8 and C5H10 differ by −CH2− group, hence they belong to same homologous series.

Answer 2

The boiling point of the hydrocarbons increases with the increasing molecular mass.

As molecular mass increases the intermolecular force of attractions (Van der Waal's force and London force) increases that require a higher amount of energy to break the bond.

Therefore, the correct order is C3H6<C4H8<C5H10
