Assertion: On moving down the group, ionization enthalpy decreases. Reason: With decrease in size of the atom, the force of attraction between the nucleus and valence electrons decreases.

Assertion : The solution of carbon tetrachloride in heptane shows positive deviation from Raoult's law. Reason : The forces of attraction between unlike molecules are stronger than those between like molecules in the solution.

Assertion : The boiling point of chloroform-acetone solution is larger than expected from ideal behaviour. Reason : The forces of attraction between unlike molecules are stronger than those between like molecules in the solution. This results in lower vapour pressure as compared to an ideal solution which is responsible for the higher boiling point.
