nH3 is more basic than PH3

Answer» Basically NH₃ is a base due to the lone pair of electrons present on the Nitrogen atom which is available for donation. On the other hand PH₃ is also a base but its basic character is less than that of NH₃ because the nitrogen in phosphorous have lone pair of electrons that are not readily available for donation.Also the P-H bonds are weaker than N-H bonds, so there’s not as much compensation for protonating PH₃. This is a result of the inert pair effect, seen in heavier elements.
