The parent structure of PH3 is trigonal pyramidal. It consists of a central phosphorus atom with three hydrogen atoms bonded to it, giving it a pyramidal shape.
The formula PH3 represents one phosphorus atom and three hydrogen atoms. Therefore, PH3 has a total of four atoms.
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.
It contains a lone pair of electrons. Hence, it can donate it thereby ,its a base. The tendency to donate the electron pairs can determine the basicity of a base. Therefore, PF3 is less basic than PH3.
With traces of P2H4 present, PH3 is spontaneously flammable in air
Phosphine, or PH3, has (quite obviously) three hydrogen atoms singly bonded to a phosphorus atom. Because of the presence of a lone pair of electrons, the phosphorus atom is sp3 hybridized, and the electron orbitals adopt a tetrahedral configuration. As mentioned earlier, one orbital is non-bonding and thus the molecular shape is trigonal pyramidal.
PH3 is an acid.It is a flammable substance.
The oxidation number of phosphorus in PH3 is -3.

The chemical symbol for phosphorus hydride is PH3.
The chemical formula for phosphorus hydrogen is PH3.
The formula PH3 represents one phosphorus atom and three hydrogen atoms. Therefore, PH3 has a total of four atoms.
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.
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.
Phosphine (PH3) forms a molecular solid in which individual PH3 molecules are held together by weak van der Waals forces.
Yes. PH3 is a trigonal pyramidalk structure like ammonia with a lone pair. There is an electronegtaivity difference between P and H and the bond dipoles and the lone pair contribution all give a smallish dipole moent,
Two equivalent Lewis structures are necessary to describe the bonding in PH3. In one structure, phosphorus forms three single bonds with hydrogen atoms, and in the other structure, phosphorus forms one double bond with one hydrogen and two single bonds with the remaining hydrogens to satisfy the octet rule.
