Question 29

What is an intermolecular force

Answer 29

A bond that holds together multiple atoms or molecules, connects different molecules to each other

Question 30

What is a intramolecular force

Answer 30

A force that holds together the atoms making up a molecule, within the molecule

Question 31

Rank the IMF’s from weakest to strongest

Answer 31

London dispersion, dipole dipole, hydrogen, ionic

Question 32

How do you tell which is stronger between two molecules in a London dispersion

Answer 32

The bigger it is, the stronger it is

Question 33

How do you tell which is stronger between two dipole-dipole interactions

Answer 33

The smaller it is and more electronegative, the stronger it is

Question 34

How do you tell which is stronger between hydrogen bonds

Answer 34

Which ever is more electronegative
