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.
What would make a good electron pair donor in the formation of a coordinate covalent bond BH3 AsH3 HCl PH3 I?
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.
Why NH3 is a liquid and PH3 is a gas?
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.
Why does ammonia have a much higher boiling point than methane?
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 acid or not?
PH3 is an acid.It is a flammable substance.

Which of these substances has a Lewis formula incorporating a double bond SbH3 HCl NH3 AsH3 PH3 HF CSe CS H2CO H2O?
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.
Why is the bond angle in PH4 higher than PH3?
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.

WHY ammonia has higher boiling point then phosphine?
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 acid or not?
PH3 is an acid.It is a flammable substance.
What is the oxidation number of PH3?
The oxidation number of phosphorus in PH3 is -3.
What is the chemical formula for phosphorus hydrogen?
The chemical formula for phosphorus hydrogen is PH3.
What is the chemical symbol for phosphorus hydride?
The chemical symbol for phosphorus hydride is PH3.
Is PH3 symmetric?
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.
