Unit 5.3

Question 1

What is a London-Dispersion bond?

Answer 1

This is where atoms or molecules can form temporary attraction to other atoms or molecules. They are caused by the electron movements.

Question 2

What is a Dipole-Dipole bond?

Answer 2

This is where atoms with permanent charges bond together. This interaction is between polar molecules.

Question 3

What is a Hydrogen bond?

Answer 3

This is the strongest bond where partial charges attract and connect with only certain atom bonds.

Question 4

Rank the three types of bonds from weakest to strongest

Answer 4

London Dispersion, Dipole-Dipole, Hydrogen

Question 5

If a molecule has as molecular dipole pointing in one direction is it polar or non polar?

Answer 5

Polar

Question 6

If a molecule has two of the same atom and no charges is this a polar or non polar atom?

Answer 6

Non-Polar

Question 7

If a molecule has two bond dipoles pointing in opposite directions cancelling each other out, is that polar or nonpolar

Answer 7

Non-polar

Question 8

What kind of bonds can all molecules form?

Answer 8

London-Dispersion

Question 9

What kinds of bonds can polar atoms form?

Answer 9

Hydrogen (sometimes) and Dipole-Dipole

Question 10

What is nessacary to form a Hydrogen bond?

Answer 10

Two of the same certain bond like O-H.

Question 11

For example what kind of bond could water and alcohol form?

Answer 11

Hydrogen because they both have O-H bonds.

Question 12

How can you determine if a molecule will be soluble in water or not?

Answer 12

If the molecule has O-H bonds, then it will be soluble in water, because water is made up of O-H bonds also.

Question 13

Since oil does not contain O-H bonds, is it soluble with water?

Answer 13

No
