nitrogen is more electronegative than the other elements, so there is a molecular dipole towards the nitrogen. NH3 is the most polar of the three.
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.
Among the options provided, AsH3 (arsine) would make a good electron pair donor in the formation of a coordinate covalent bond. This is because arsenic has a lone pair of electrons available for donation, allowing it to act as a Lewis base and form a coordinate covalent bond with a Lewis acid.
NH3 (ammonia) is a liquid at room temperature due to intermolecular hydrogen bonding that holds ammonia molecules together. PH3 (phosphine) is a gas at room temperature because its intermolecular forces are weaker, resulting in lower boiling point compared to NH3.
NH3 Has a Higher EN than PH3 and will exhibit Hydrogen bonding. Because of this, NH3 has a stronger bond with PH3 so its boiling point is higher (harder to break bonds, more temperature required).
PH3 is an acid.It is a flammable substance.

HCl, NH3, PH3, HF, CS, H2CO, H2O have Lewis formulas that do not incorporate a double bond. CS2 has a Lewis formula with a double bond between the C and S atoms.
The bond angle in PH4 is higher than PH3 because PH4 has a tetrahedral molecular geometry with bond angles of about 109.5 degrees, while PH3 has a trigonal pyramidal molecular geometry with bond angles of about 107 degrees. This difference in bond angles is due to the presence of an additional hydrogen atom in PH4 compared to PH3.

NH3 exhibits hydrogen bonding in addition to dispersion forces. This significantly increases the intermolecular force, and raises the boiling point. PH3 does not exhibit hydrogen bonding and the dominant intermolecular force holding these molecules together is dispersion forces. (Dispersion forces also known as Van Der Waal Force)

PH3 is an acid.It is a flammable substance.
The oxidation number of phosphorus in PH3 is -3.
The chemical formula for phosphorus hydrogen is PH3.
The chemical symbol for phosphorus hydride is PH3.
No, PH3 is not symmetric. The molecule has a pyramidal shape due to the lone pair on the central phosphorus atom. This asymmetry contributes to the overall molecular geometry of PH3.
