Intermolecular interactions: Permanent dipoles

Question 1

true or false: it is possible for molecules with permanent dipoles to interact with each other.

Answer 1

true: if the dipoles are arranged correct, then there will be a favourable interaction

Question 2

a favourable interaction is when

Answer 2

the dipoles are aligned in a way that the partial charges of the molecules attract each other, so an intermolecular interaction is possible

Question 3

permanent dipole interactions are less

Answer 3

significant than London forces because the dipoles are not always aligned correctly to give a favourable interaction, while London forces ALWAYS do

Question 4

permanent dipole-permanent dipole and permanent dipole-induced dipole interactions are called

Answer 4

permanent dipole-dipole forces

Question 5

it is possible for permanent dipoles to

Answer 5

induce a dipole in a neighbouring molecule

Question 6

the orgigin of London forces are

Answer 6

instantaneous dipole-induced dipole interaction

Question 7

the origin to permanent dipole forces are

Answer 7

permanent dipole-dipole interaction

Question 8

the term ‘van der Waals force’ includes

Answer 8

all intermolecular interactions
