With the increasing molecular mass of a liquid the velocity:

With the increasing molecular weight of a liquid, the viscosity

With the increasesing molecular weight of a liquid the viscosity

Which of the following decreases with increase in molecular mass for a liquid?

Assertion : Solubility of alcohols in water decreases with the increase in the molecular mass. Reason : The increase in the size of the alkyl group increases the polar nature of O-H group.

If we increase the molecular mass of alcohol , its solubility will

Assertion (A) : The active mass of pure solid and pure liquid is taken unity. Reason (R) : The active mass of pure solids and liquids depends on the density and molecular mass. The density and molecular of a mass of pure liquids and solids are constant.

Assertion (A) : The active mass of pure solid and pure liquid is taken unity. Reason (R) : The active mass of pure solids and liquids depends on the density and molecular mass. The density and molecular of a mass of pure liquids and solids are constant.

Explain the variation of melting points and boiling points with increase in molecular mass of alkanes.
