Question

phosphate has lower boilling point than ammonia.why?​

Answer 1

Answer:in ammonia there are 3 hydrogen atoms attached to electronegative Nitrogen.this causes the formation of hydrogen bonds which makes ammonia less volatile than phosphate which does not form hydrogen bonds

Answer 2

Answer:

PH3 has a lower boiling point than ammonia due to its inability to assorted via intermolecular hydrogn bonding. This is because phosphorus is bigger have bigger size as compare to nitrogen thus have weak bonding with hydrogen.
