Introduction
• The Bond Order is given by the number of bonds between the two atoms in a molecule. • It is correlated with bond length and bond enthalpy.
Pre-Requisites:
Chemical bond, ionic bond
Activity:
Stronger bonds need greater energy to break.
Real Life Question:
How to find out the strength of bonding between atoms in a molecule?

What you learn in Theory:
The Bond Order is given by the number of bonds between the two atoms in a molecule. Isoelectronic molecules and ions have identical bond orders.
What you learn in Practice:
A higher bond order correlates with a stronger bond.
