Chapter 11, Problem 11.118QP

For the carbon and nitrogen family hydrides, we have the following boiling points:

Carbon Family,°C	Nitrogen Family,°C
CH4, −164	NH3, −33
SiH4, −112	PH3, −88
GeH4, −88	AsH3, −55
SnH4, −52	SbH3, −17

Account for the following:

1. a The general trend in the boiling points of the binary hydrides.
2. b The unusual boiling point of ammonia.
3. c The observation that the nitrogen family hydrides have boiling points that are notably higher than those of the carbon family.
