Solubility and vapour pressure intermolecular forces

Question 1

Polar solutes in polar solvents or non polar solutes in non polar solvents

Answer 1

if they are capable of forming complimentary intermolecular forces, they are easily able to form those intermolecular forces
Little resistance of mixing between molecules

Question 2

polar solutes in non polar solvents

Answer 2

Polar solutes form stronger forces of attraction with each other than they do with non polar molecules
resulting in a resistance between the two

Question 3

non polar solutes in polar solvents

Answer 3

same as others

Question 4

An increase in melting boiling points is likely due to

Answer 4

An increase in the number of electrons (molecular size)

Question 5

What does vapour pressure measure

Answer 5

Measure of the tendancy of a substance to evaporate

Question 6

Relationship between intermolecular forces and vapour pressure

Answer 6

Weak im forces = liquid easily evaporates = high vapour pressure
Strong intermolecular forces = liquid doesnt easily evaporate = low vapour pressure
