Is PH3 is stronger than NH3?
PH3 (phosphine) is considered to be a weaker base compared to NH3 (ammonia) because the electronegativity of phosphorus is greater than nitrogen, making the lone pair on phosphorus less available for donation. This results in NH3 being a stronger base than PH3.
Why does PH3 have a higher vapor pressure then NH3?
PH3 has a higher vapor pressure than NH3 due to the larger size and greater molecular weight of phosphorus compared to nitrogen. This results in weaker van der Waals forces between PH3 molecules, allowing them to escape and become a gas more easily than NH3 molecules.
Which compound is more like an ionic compound NH3 or PH3?
NH3 is more like an ionic compound compared to PH3 because ammonia (NH3) displays some characteristics of ionic bonding due to its ability to accept and donate protons, while phosphine (PH3) has predominantly covalent bonding due to similar electronegativities of phosphorus and hydrogen.
Why is bond angle in ph3 less than that in nh3?
Both PH3 and NH3 have 3 bonding pairs and 1 lone pair of electrons around the central atom, and so are both trigonal pyramidal in shape. The bond angle in NH3 is less than 109.5º and that in PH3 is less than that in NH3 (maybe around 109º). The reason for this has to due with electronegativity. The N atom is more electronegative than the P atom and thus electron density of N's bonding electrons are closer to the N, and so they exert a greater repulsion on each other. This greater repulsion compared to that seen PH3 makes the bond angle slighter greater in NH3. P being less electronegative than N doesn't draw it's electrons as close so they don't repel as much.
What is the formula for liquid ammonia?
The formula for liquid ammonia is NH3.

Why pure NH3 does not burn in air but impure PH3 burn in air?
With traces of P2H4 present, PH3 is spontaneously flammable in air
