Concept explainers
(a)
Interpretation:
The given compounds are to be arranged in the order of increasing boiling point.
Concept introduction:
The boiling point is the temperature in which the conversion of a liquid into a vapor state takes place. At this temperature, the liquid’s vapor pressure becomes equal to the external pressure surrounding the liquid. The boiling point of a molecule depends upon the interactions that result from permanent or induced dipoles.
(b)
Interpretation:
The given compounds are to be arranged in the order of increasing boiling point.
Concept introduction:
The boiling point is defined as a temperature at which the conversion of a liquid into a vapor state takes place. At this temperature, the liquid’s vapor pressure becomes equal to the external pressure surrounding the liquid. The boiling point of a molecule depends upon the interactions that result from permanent or induced dipoles.
(c)
