Question

Identify the molecular interaction based on the electronegativity difference for CaO ?

Answer 1

Explanation:

Rule of Thumb: Predicting Bond Types

As a "rule of thumb", electronegativity differences can be used to predict if a bond will be covalent, polar covalent or ionic. If the difference in χ between two bonding atoms is less than 1/2, they are of very similar electronegativity and it is a covalent bond.
