Chemistry - CHEMICAL BONDING Question with Solution | TestHub

(i) Three equatorial $\mathrm{P}-\mathrm{C}\mathrm{l}$ bonds make an angle of $120°$ with each other is correct.

(ii) Two axial $\mathrm{P}-\mathrm{C}\mathrm{l}$ bonds make an angle of $180°$ with each other.

(iii) Axial $\mathrm{P}-\mathrm{C}\mathrm{l}$ bonds are longer than equatorial because according to Bent’s rule the hybrid orbitals that contain more $\mathrm{p}-$character or less $\mathrm{s}-$character are placed on axial position and have more bond length.

(iv) $\mathrm{P}\mathrm{C}{\mathrm{l}}_5$ molecule is reactive (W) is the incorrect answer.
