Question 1

What is difference between polar and non-polar molecules?

Answer 1

Polar molecules have electrons shared unequally and Nonpolar molecules share electrons equally.

Question 2

Dipole-dipole bonds form between what type of molecule?

Answer 2

They form between polar molecules

Question 3

London Dispersion forces form between what type of molecule?

Answer 3

Any/ all molecules

Question 4

Hydrogen bonds form between what types of molecules?

Answer 4

They form between molecules that have O-H, N-H, or F-H bonds.

Question 5

If the arrows on a graph are all pointing in one direction, what does that mean?

Answer 5

It means that the molecule is polar.

Question 6

What is the ranking from weakest bond to strongest bond?

Answer 6

London Dispersion, dipole-dipole, and then hydrogen bonds

Question 7

What part of the water molecule do hydrogen bonds form?

Answer 7

The form between two water molecules. They will connect the proton and electron.
