bonding and structure

Question 1

what are the three types of intermolecular forces?

Answer 1

induced dipole dipole interactions (london forces), permanent dipole dipole interactions, and hydrogen bonds.

Question 2

what are factors that effect london forces?

Answer 2

amount of electrons in a molecule or atom

Question 3

comment on the relative strength of london forces.

Answer 3

it is the weakest intermolecular force

Question 4

what molecules/ atoms experience london forces?

Answer 4

all molecules and atoms experience london forces, even polar molecules.

Question 5

what is required for permanent dipole interactions to take place?

Answer 5

unsymmetrical polar molecules.

Question 6

comment on the relative strength of a permanent dipole interaction.

Answer 6

stronger than london forces, weaker than hydrogen bonds.

Question 7

what conditions are required for hydrogen bonding?

Answer 7

1) A hydrogen atom bonded to a strongly electronegative element.
2) The electronegative element must have at least 1 lone pair of electrons ( oxygen, nitrogen, fluorine)
