Question

Both ammonia (nh3) and phosphine (ph3) are soluble in water. Which is least soluble and why?.

Answer 1

Hence, ammonia is soluble in water. But in phosphine (PH3) ( P H 3 ) , P has hydrogen and lone pair of electrons but phosphorous and hydrogen have similar electronegativity. So it does not form hydrogen bonding with water, only a dipole-dipole interaction which is a weaker interaction.

Goodluck, have a good day

Answer 2

Step-by-step explanation:

Hence, ammonia is soluble in water. But in phosphine (PH3) ( P H 3 ) , P has hydrogen and lone pair of electrons but phosphorous and hydrogen have similar electronegativity. So it does not form hydrogen bonding with water, only a dipole-dipole interaction which is a weaker interaction.
