1. A data set in which there is a considerable closeness among the values
A. Accurate
B. Approximate
C. Estimate
D. Precise
2. A type of Van der Waals forces of attraction resulting from the tendency of molecules to align themselves
with oppositely charged ends of their neighbour
3. A type of Van der Waals forces of attraction which involves permanent dipoles inducing polarity in non-polar
molecules
4. A type of Van der Waals forces of attraction which involves the dispersion of charges to induce polarity
between non-polar molecules
5. The intermolecular forces of attraction responsible for the solubility of non-polar molecules such as Iodine in
solution by the addition of salts
A. Debye
B. Ion-dipole interaction
C. Ion-induced dipole interaction
D. H-bonds
6. This is responsible for the solubility of ionic crystalline substance in polar solvents like water
7. H-bond is the interaction between a molecule containing a hydrogen atom and a strongly electronegative
atom such as fluorine, oxygen and nitrogen. This is/are true statements regarding H-bonds
I. Stronger than ionic bonds
II. Responsible for the formation of water molecules
III. Can be both occurring as an intramoleecular and intermolecular force of attraction

10. Gas X is an ideal gas occupying a volume of 15ml at a temperature of 55°F and a pressure of 700mmHg.
What is the volume of a gas at 0° and 800mmHg?
11. At constant pressure a gas occupies volume of 50ml at a temperature of 40°C. What will be the volume
occupied by the gas at 90°C
12. A gas law which states that gases of equal volumes at the same temperature and pressure contain the
same number of molecules
