Sub Topic Name : Hybridization Of Elements Involving D Orbitals |

Introduction
• The elements present in the third period contain d orbitals in addition to s and p orbitals. • Possible hybridisation is between either 3s, 3p and 3d or 3d, 4s and 4p due o similar energies. • Sp3d hybridization is found in PCl5 molecule. It is trigonal bypyramidal in shape • Sp3d2 hybridisation is found in SF6 molecule. It is octahedral in shape.
Pre-Requisites:
Covalent bond, polyatomic molecule , orbital
Activity:
Hybrids for example (animals, plants) are mixture of two or more individual types.
Real Life Question:
How do hybrids form?

What you learn in Theory:
Different types of hybridization give different geometries of polyatomic molecules.
What you learn in Practice:
Hybridisation is intermixing.
