(a)
Interpretation:
What is the freezing point of the given liquid must be explained?
Concept Introduction:
Freezing point of a liquid is the temperature at which the vapor pressure of the liquid is equal to the vapor pressure of solid.
(b)
Interpretation:
What is the boiling point of the liquid must be explained?
Concept Introduction:
Boiling point is the temperature at which a liquid starts boiling to vapor and until all the liquid is not boiled off temperature remains same. The vapor pressure of the liquid is equal to atmospheric pressure.
(c)
Interpretation:
Which out of heat of fusion or heat of vaporization is greater must be explained?
Concept Introduction:
Both heat of fusion and heat of vaporization is done at constant temperature with the help of latent heat.

- Unshared, or lone, electron pairs play an important role in determining the chemical and physical properties of organic compounds. Thus, it is important to know which atoms carry unshared pairs. Use the structural formulas below to determine the number of unshared pairs at each designated atom. Be sure your answers are consistent with the formal charges on the formulas. CH.
