(a)
Interpretation:
Whether the melting point increase or decrease with the increase in the molar mass of Group
Concept introduction:
The melting point of a compound is the temperature at which solid converts into liquid form. Melting point depends upon the intermolecular forces of attraction between the molecules and is also directly proportional to the molar mass of the compound.
Answer to Problem 59E
The melting point generally increases with the increase in the molar mass of Group
Explanation of Solution
The melting point of the hydrogen compounds of Group
The order of melting point of hydrogen compounds of Group
The melting point increases with increase in the molar mass of Group
(b)
Interpretation:
Whether the boiling point increases or decreases with the increase in the molar mass of Group
Concept introduction:
The boiling point is the temperature at which the vapor pressure of the liquid becomes equal to the atmospheric pressure. The boiling point of a compound is directly proportional to its intermolecular forces of attractions and the molar mass of the compound.
Answer to Problem 59E
The boiling point generally increases with the increase in the molar mass of Group
Explanation of Solution
The boiling point of the hydrogen compounds of Group
The order of boiling point of hydrogen compounds of Group
The boiling point increases with increase in the molar mass of Group
(c)
Interpretation:
Whether the heat of fusion increases or decreases with the increase in the molar mass of Group
Concept introduction:
The heat of fusion of a compound is the amount of energy required to convert solid into liquid form. The heat of fusion depends upon the intermolecular forces of attraction between the molecules and is also directly proportional to the molar mass of the compound.
Answer to Problem 59E
The heat of fusion generally increases with the increase in the molar mass of Group
Explanation of Solution
The heat of fusion of the hydrogen compounds of Group
The order of heat of fusion of hydrogen compounds of Group
The heat of fusion increases with increase in the molar mass of Group
(d)
Interpretation:
Whether the heat of vaporization increases or decreases with the increase in the molar mass of Group
Concept introduction:
The heat of vaporization is the amount of heat required to convert the liquid state to the gaseous state. The heat of vaporization of a compound is directly proportional to its intermolecular forces of attractions and the molar mass of the compound.
Answer to Problem 59E
The heat of vaporization generally increases with the increase in the molar mass of Group
