Molecular Polarity vs Bond Polarity

Question 1

How to show polarity in a bond

Answer 1

To show polarity in a bond, we can use δ- and δ+ symbols which 
represent partial negative and positive charges or +–> 
representing a dipole moment. The head of arrow points to more electronegative atom

Question 2

Polar bond

Answer 2

INequal sharing since polar bears don’t share!!!

Question 3

Molecules can be non-polar when bonds are polar

Answer 3

This is because the dipole moment (basically vectors) cancel each other out by going in opposite directions. Bonds are polar when you subtract electronegativities. Molecules are polar based on dipole moments

Question 4

POlarity affects…

Answer 4

Solubility. Polar molecules dissolve well in water.
