पर्याय
increase
decrease
उत्तर
As the molecular masses of hydrocarbons increase, their boiling points increase and melting points increase.
Explanation:
With an increase in molecular mass, hydrocarbons have stronger van der Waals forces, requiring more energy to break intermolecular bonds, leading to higher boiling and melting points.
