Intermolecular Forces

Question 1

Dipole-Dipole definition

Answer 1

Attraction between 2 molecules, a negative to a positive end.

Question 2

London Dispersion definition:

Answer 2

One end of molecule is partially negative and the other end is partially positive.

Question 3

Weakest to strongest of Intermolecular forces:

Answer 3

London Dispersion, Dipole-Dipole, Hydrogen Bonds, Ionic Bonds, and Covalent Bonds

Question 4

How is a molecule polar?

Answer 4

It has O-H, N-H, and F-H at the ends of their structure.

Question 5

How is a molecule non-polar?

Answer 5

It will NOT have O-H, N-H, or F-H at the ends of their structures. They’ll have different atoms at the end.

Question 6

What type of intermolecular attraction will polar form?

Answer 6

Dipole-Dipole because Polar is asymmetrical which means it had a positive and negative end.

Question 7

What type of intermolecular attraction will non-polar form?

Answer 7

London Dispersion because it’s partial positive and partial negative and it’s symmetrical (not fully positive and negative attractions).

Question 8

When will a molecule be soluble in water based in its structure?

Answer 8

It will be solvable if it it is polar like water and dissolve. If it’s non-polar then it will not dissolve and separate itself from the water.
