Question 1

What type of reaction can any atoms/molecules form?

Answer 1

London dispersion

Question 2

What is electronegativity?

Answer 2

It affects how polar/non-polar forces are by how strong the pull is on electrons

Question 3

What are london dispersion forces?

Answer 3

Temporary dipoles that create a partial force.

Question 4

What is a hydrogen bond?

Answer 4

An extremely strong polar bond (O-H, N-H, F-H)

Question 5

Rank the 3 forces strongest to weakest

Answer 5

Hydrogen bonds, dipole-dipole, london dispersion

Question 6

What is a molecule pair?

Answer 6

Must obtain a polar covalent bond and have asymmetrical ends

Question 7

How can you determine which way to draw a bond dipole?

Answer 7

The direction of the dipole will face the direction of the molecule with a higher EN

Question 8

Why is it important to take both the polarity of the bonds and the shape of the molecule into consideration when determining the polarity of the molecule?

Answer 8

To be able to determine whether or not a molecule is electronegative.

Question 9

Can an element have a partial charge?

Answer 9

Yes, depending on if other elements are taking or donating electrons.

Question 10

Do dipoles change direction when moved?

Answer 10

No, they still face the same way
