The ability to flow or stickiness

Question 13

Solvation

Answer 13

Ability to dissolve in water

Question 14

Boiling/ melting point

Answer 14

Higher as the ims increases

Question 15

How IMFs affect St, V, S BP, MP

Answer 15

As the imf increases, the … Increases (linear)

Question 16

What are the strengths of IMF

Answer 16

From weakest to strongest
Londoon dispersion forces
Dipole forces
Hydrogen bonding

Question 17

How does the size of the molecule affect the IMF

Answer 17

The larger the molecule the more permanant the electrons will stay on one side

Bond angle Q120

Question 22

Big bent

Answer 22

2 central atoms with a double bond connected to the central atom and one lone pair

Question 23

Linear shape

Answer 23

Straight line with atoms on each side

Bond angle 180

Question 24

London dispersion theory

Answer 24

The buildup of electrons temporarily on one side of the molecule (teacher vs student)
ONLY NONPOLAR MOLECULES

Question 25

Dipole force

Answer 25

Two opposite sided molecules that have a partial permanant seperation of charge because the electrons are not evenly shared
ALL POLAR MOLECULES EXCEPT h/f h-n h-o

Question 26

Hydrogen bonding

Answer 26

Polar bond only woth h-f h-n h-o

Creates a very strong dipole because no other electrons counteract

When is it a polar molecule?

Answer 28

If there is a polar bond
If there is a lone pair
If there is a polar and nonpolar bond

Answer 29

Want 8

Starts with the column it is in on the periodic table
