Question

EXPLAIN THE HYBRIDIZATION INVOLVED IN PCL5 MOLECULE??​

Answer 1

Answer:

In PCl5 molecule the central atom is P. The five sp3d hybrid orbitals are singly occupied . These hybrid orbitals overlap with singly filled 3pz atomic orbital of five Chlorine atom to form five sigma bond (P- Cl). Geometry of PCl5 molecule is trigonal bipyramidal.

Answer 2

In PCl₅, trigonal bipyramidal hybridisation is found.

Explanation:

In PCl₅

• the central metal atom P is having Z=15 with  electronic configuration 1s²,2s²,2p⁶,3s²,3p³

• atom Cl is having Z= 17 with electronic configuration 1s²,2s²,2p⁶,3s²,3p⁵

• According to VSEPR theory, it is having hybridization sp³d
• 3 P-Cl bond lies in one plane and  make an angle with each other of 120°C
• Two axial bonds 2 P-Cl bonds lies above the equatorial plane and angle of 90°C.
• It forms weaker bonds resulting in reactive  PCl₅.
• PCl₅ is having trigonal bipyramidal hybridsation.
