Introduction
• In reality no bond or a compound is either completely covalent or ionic. • Covalent bonds are polar covalent or non polar covalent.
Pre-Requisites:
covalent bond, ionic bond,
Activity:
Batteries, magnet
Real Life Question:
Are covalent molecules completely covalent in nature?
Key Words / FlashCards
| Key Words | Definitions (pref. in our own words) |
|---|---|
| Dipole moment | Dipole moment is the phenomenon when there is shift in the arrangement of the electrons such that the electronegative element has the electrons closer to it. |
Learning aids / Gadgets
| Gadgets | How it can be used |
|---|---|
| Battery, magnet | Like battery and magnet, molecules also have a negative and positive end making a dipole. |
Real life uses :
All molecules have polarity, e.g. water, this polarity makes it a good solvent.

Practical examples around us
| Examples | Explainations |
|---|---|
| Batteries, magnets | Similar to batteries with positive and negative poles, covalent molecules also have two poles, positive and negative making a dipole. |
What you learn in Theory:
All molecules have covalent and ionic character.
What you learn in Practice:
Polarity of molecules makes them solvents.
