(a)
Interpretation:
The substance in the set with highest boiling point needs to be determined.
Concept Introduction:
The boiling points of various substances can be explained by considering intermolecular attractive forces which held the constituents together. Intermolecular attractive forces are highest for solids and lowest for gases. There is no force of attraction between gas molecules. Intermolecular attractive forces are moderate in liquid. In liquid substance, the boiling point depends on H-bonding.
(a)
Explanation of Solution
Among CaCl2, H2 and S8, the boiling point of CaCl2 is highest. Because CaCl2 is an ionic compound, the particles CaCl2 are held together tightly by strong electrostatic forces between opposite ions. Whereas H2 is a gas molecule and S8 is a molecular solid.
(b)
Interpretation:
The substance in the set with highest boiling point needs to be determined.

Explanation of Solution
Among Ne, P4 and KCl, the boiling point of KCl is highest. Because KCl is an ionic compound, the particles KCl are held together tightly by strong electrostatic forces between opposite ions. Whereas Ne is a gas molecule and P4 is a molecular solid.

(c)
Explanation of Solution
Among N2, NH3 and H2, the boiling point of NH3 is highest. Because NH3molecules exhibited strong H-bonding with another NH3 molecules and exists as an associated liquid. Whereas both N2 and H2 exist in a gaseous state.
