Hydride of nitrogen family have general formula M H 3 . Of the following hydrides which has the lowest boiling point?
Options
- AN H 3
- BP H 3
- CS b H 3
- DA s H 3
Correct answer
B. P H 3
Step-by-step solution
P H 3 has the lowest boiling point because it does not form Hydrogen bond. B i H 3 > S b H 3 > N H 3 > A s H 3 > P H 3 . (order of boiling points)
