Explain the bond lengths of all P-Cl bonds in `PCl _(5)` molecule.

Text Solution

AI Generated Solution

To explain the bond lengths of all P-Cl bonds in the PCl5 molecule, we can follow these steps: ### Step 1: Understand the Structure of PCl5 PCl5 (phosphorus pentachloride) has a trigonal bipyramidal molecular geometry. In this structure, there are two types of positions for the chlorine atoms: axial and equatorial. **Hint:** Remember that the geometry of a molecule can influence bond lengths due to the arrangement of atoms. ### Step 2: Identify the Bond Types ...

  • Why all P - F bonds in PF_(5) are not equivalent?

    A
    `PF_(5)" has "sp^(3)d` hybridisation, out of five P-F bonds three are equatorial which have different lengths.
    B
    `PF_(5)" has "sp^(3)` hybridisation, out of five P-F bonds two are equatorial which have different lengths.
    C
    Out of five P-F bonds two are axial and three equatorial. All five bonds have different bond lengths.
    D
    `PF_(5)` is made up of two types of bonds namely covalent and coordinate, hence are not equivalent.
