Introduction
• Bond angle is defined as the angle between the orbitals containing bonding electron pairs around the central atom in a molecule • Bond angle is expressed in degree which can be experimentally determined by spectroscopic methods. • Bond angle helps to determine the shape of the molecules.
Pre-Requisites:
Chemical bond, ionic bond, orbitals
Activity:
All objects have angles within their structures which give them a distinctive shape.
Real Life Question:
How can you find out the shapes of objects?
