Question

why ammonia is a liquid and ph3 is a gas

Answer 1

NH 3is a liquid at room temperature while PH 3 is a gas. This is because in NH3 the molecules are associated to each other through intermolecular hydrogen bonds whereas in PH3 there is no such type of association between the molecules, hence, it exist as gas.

Answer 2

Answer:

NH3 is liquid but PH3 ( phosphine) is gas use of the presence of hydrogen bonding and its forms only with F , O, N electronegativity of NH3 is liquid but ph3 is gas
