PH3 has the lowest boiling point because it does not form Hydrogen bond. textB texti textH3 > textS textb textH3 > textN textH3 > textA texts textH3 > textP textH3 . (order of boiling points)

Q. Hydride of nitrogen family have general formula $M H_{3}$ . Of the following hydrides which has the lowest boiling point?

$N H_{3}$

$P H_{3}$

$S b H_{3}$

$A s H_{3}$

$P H_{3}$ has the lowest boiling point because it does not form Hydrogen bond.

$B i H_{3} > S b H_{3} > N H_{3} > A s H_{3} > P H_{3} .$
