Nope, the bonds are covalent because phosphorus and hydrogen are both non-metals, and that's what happen when non-metals bond. Now, with that said, when you have a bunch of PH3 molecules together, there will be some hydrogen bonding between molecules, because PH3 is polar. It's polar because you have a difference in charge across the length of that molecule, which is a result of the hydrogens' 1 and only electron tied up in the covalent bond with phosphorus, meanwhile phosphorus has 1 electron pair unshared (see Lewis structures.) This means the positive end of one molecule will be attracted to the negative end of another molecule. This intermolecular attraction is called hydrogen bonding, and it explains many physical properties of polar substances which contain hydrogen.

What compounds will have a dipole moment ch4 c2h6 xef4 sf6 ph3?
Out of the given compounds: CH4 (methane) is nonpolar and does not have a dipole moment. C2H6 (ethane) is also nonpolar and does not have a dipole moment. XeF4 (xenon tetrafluoride) is a polar molecule due to its square planar geometry with the fluorine atoms creating a net dipole moment. SF6 (sulfur hexafluoride) is nonpolar and does not have a dipole moment. PH3 (phosphine) is polar due to the lone pair on phosphorus creating a net dipole moment.
How many atoms does the formula PH3 have?
The formula PH3 represents one phosphorus atom and three hydrogen atoms. Therefore, PH3 has a total of four atoms.
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.
What is the systematic name for 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.
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
What are ph3's intermolecular forces?
PH3 (phosphine) exhibits London dispersion forces as its primary intermolecular force. Phosphorus is more electronegative than hydrogen, creating a weak dipole moment in the molecule, leading to additional dipole-dipole interactions. Additionally, PH3 can engage in hydrogen bonding with other molecules containing a hydrogen bonded to a nitrogen, oxygen, or fluorine atom.
Why is ph3 Dispersion and Dipole-Dipole?
PH3 has a dipole moment , of 0.58 D. Therefore there will be dipole dipole interactions. All molecules experience London dispersion forces as these are caused by the interaction of instantaneous dipoles due to the movement of electrons within the molecules.
Does PH3 have dipole moment?
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,

What is the oxidation number of PH3?
The oxidation number of phosphorus in PH3 is -3.
What is the chemical symbol for phosphorus hydride?
The chemical symbol for phosphorus hydride is PH3.
What is the chemical formula for phosphorus hydrogen?
The chemical formula for phosphorus hydrogen is PH3.
How many atoms does the formula PH3 have?
The formula PH3 represents one phosphorus atom and three hydrogen atoms. Therefore, PH3 has a total of four atoms.
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.
What determines whether a molcule has an overall dipole moment?
Generally if a molecule contains polar bonds and the bond dipole moments do not cancel each other out then that molecule will have an overall dipole moment. Bond dipoles arise when there is a significant difference in electronegativity between the atoms in the bond. There some cases such as phosphine PH3 where the lone pair can make a significant contribution to the molecular dipole moment.
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.
