Introduction
Nature of molecules depends on the dipole moment between the atoms.
Pre-Requisites:
Basic knowledge of Electric Dipole
Activity:
Make a list of polar and non polar molecules.
Real Life Question:
Why CO2 is non polar and H2O is polar?
Key Words / FlashCards
| Key Words | Definitions (pref. in our own words) |
|---|---|
| Polar molecules | These molecules have permanent dipole moment even in the absence of the electric field. |
Learning aids / Gadgets
| Gadgets | How it can be used |
|---|---|
| Text book | You can learn about this more from the text book. |
Real life uses :
We can determine nature and polarity of any molecule, which may be useful in chemical reactions.
Places to visit :
You can visit your chemistry lab to see various types of polar and non polar molecules.
Practical examples around us
| Examples | Explainations |
|---|---|
| Every compound | Every molecule or compound present around us is polar or non polar. |
What you learn in Theory:
Those molecules in which centers of charges coincide, have zero dipole moment in the absence of electric field & those molecules in which centers do not coincide, have non zero dipole moment.
What you learn in Practice:
Molecules are polar or non polar depending on the dipole moment of the compound.
