Which of the following correctly represents the relationship between the number of carbon atoms and the boiling point in a homologous series of alkanes?
As the number of carbon atoms increases, the boiling point decreases.
As the number of carbon atoms decreases, the boiling point increases.
As the number of carbon atoms increases, the boiling point increases.
The number of carbon atoms does not affect boiling point.
Explanation
Boiling point increases with increasing number of carbon atoms due to stronger intermolecular forces.
