Question
Rank the vapor pressure for the following hydrides of Group Velements.
(lowest vapor pressure) PH3AsH3SbH3NH3 < SbH3PH3NH3AsH3 < AsH3SbH3NH3PH3 < AsH3PH3SbH3NH3 (highest vapor pressure)
Which of the following would be the best solvent forNH3 and why?
CH3(CH2)4CH3,CCl4, CH3OH,BrCH2CH2CH3.
The following data for the hydrides of group V are given:
Explanation / Answer
The higher the boiling point -> higher intermolecular forces-> low vapor pressure SbH3 has the highest boiling point -> lowest vapor pressure Next: NH3 Next: AsH3 Finally: PH3 has the lowest boiling point -> highest vaporpressure NH3: has hydrogen bonding. Like dissolves like. Ch3OH is the bestsolvent because it also has hydrogen bonding.
