is sbh3 boiling point higher than nh3

Ammonia (NH3) has a higher boiling point than stibine (SbH3) since ammonia can form weak hydrogen bonds. Hydrogen bonding explains why water, a very small molecule, can have a boiling point of 100 degrees Celsius. The difference between ammonia and water, in terms of hydrogen bonding, is due to the fact that the oxygen in a water molecule has two lone pairs of electrons (able to form more bonds), than the nitrogen in ammonia that only has one pair of free electrons (less hydrogen bonds can be formed)
