Content after Exam 5

Question 1

ion-dipole force

Answer 1

when a ion (charged atom) is attracted to a certain side of a molecule with a dipole.
ex: chlorine (-1) is attracted to the positive side of a H2O molecule

Question 2

dipole-dipole forces

Answer 2

when the positive side of a polar (has dipole) molecule is attracted to the negative side of another molecule

Question 3

London dispersion forces

Answer 3

when electrons are forced to one side of a molecule/atom, creating a temporary dipole

Question 4

boiling point

Answer 4

the point where a liquid starts turning to gas

Question 5

polarizability

Answer 5

the ability to create a temporary dipole

Question 6

all molecules have what force

Answer 6

London dispersion forces

Question 7

hydrogen bonding

Answer 7

• a special type of dipole-dipole force
• when H is bonded to F, O, N, it creates a strong dipole
