Question

06. The molecular formula of a hydrocarbon is C4H8 what would be the molecular formula
reche next member in this homologous series? (1)​

Answer 1

ANSWER

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 C
