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.
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.
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.
Which boiling point is higher PH3 or AsH3?
The boiling point of AsH3 (Arsine) is higher than that of PH3 (Phosphine) due to the higher molecular weight of AsH3 compared to PH3. Stronger Van der Waals forces of attraction between molecules in AsH3 result in higher boiling point.
Is PH3 is stronger than 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

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 NH3 is more basic than NF3?
NH3 is basic while BiH3 is only feebly basic because: 1) the atomic size of N is less than Bi.ther fore it has smaller size than Bi. 2)the electron density of N is much more than Bi due to small size. 3)therfore because of small size and high electronegativity of N the tendancy to donate its lone pair of electon in NH3 will be much higher than Bi in BIh3.
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 is phosphine non polar?
The shape is trigonal pyramidal Polarity is non-polar
What is the chemical formula for trihydrogen mononitride?
The chemical formula for trihydrogen mononitride is H3N. This compound consists of three hydrogen atoms bonded to one nitrogen atom. It is also known as ammonia, a common household chemical with a pungent odor.
What acts as an acid in the following reaction NH 3 plus PH 3 - NH 2- plus PH 4 plus?
As you have it written NH3 donates a proton to the solution and this hydrogen ion is picked up by PH3 to make PH4; so NH3 is the acid here. ( though this reaction seems odd to me )
