Answer 1

bonds between atoms of different electronegativity

Question 2

what is the measure of net dipole polarity?

Answer 2

Dipole Moment

Question 3

What im force is between an ion and a partial charged region of a polar molecule?

Answer 3

Ion-Dipole force

Question 4

What is the relation between dipole moments and boiling points?

Answer 4

Higher Dipole moments=higher imfs=higher boiling point

Answer 7

London dispersion, dipole-dipole, hydrogen bonds, Ion dipole.

Question 8

What is a measure of a liquid’s resistance to flow?

Answer 8

Viscosity

Question 9

What is the relation between viscosity and imfs?

Answer 9

Higher viscosity=higher imfs

Define heat of fusion

Answer 10

the amount of energy needed to overcome the imfs to convert a solid into a liquid

Question 11

What is the relation between vapor pressure and imfs?

Answer 11

The higher the imfs the lower the vapor pressure
