What are van der Waals' forces?

Which are the different types of van der Waals' forces?

Assertion : In alcohols, the boiling point decreases with decrease in the branching of the carbon chain. Reason : -There is the increase in van der Waals/ forces between the number of carbon atoms with decrease in the surface area.

Van der Waal's forces are attraction inter molecular forces. Write the names of any two types of van der Waal's forces.

Van dar Waal's equation explains the behaviour of rea gases. What does the van der Waal's constant 'a' indicate?

Assertion:Langmuir adsorption is a single layer phenomenon.Reason: It is due to van der Waals forces.

Assertion :In physical adsorption, enthalpy of adsorption is very low. Reason: In physical adsorption, attraction between gas molecules and solid surface is due to weak van der Waals forces.

Indicate whether the following statement is true or false. Justify your answer. In the van der Waal's equation. [p+(n^2 a)/V^2] (V-n b)=nRT the constant a reflects the actual volume of the gas molecules.
