What type of bond is PH3?

PH3 is a covalent bond, specifically a polar covalent bond. This is because phosphine (PH3) is formed when phosphorus shares its electrons with hydrogen to complete its valence shell, creating a partial negative charge on phosphorus and a partial positive charge on hydrogen.


Is PH3 a ionic or covalent bond?

Neither. It is hydrogeneous.


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.


What type of solid will Ph3 form?

Phosphine (PH3) forms a molecular solid in which individual PH3 molecules are held together by weak van der Waals forces.

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.


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.
