Question 1

london dispersion

Answer 1

temporary attraction to other atoms/molecules, present in all molecules

Question 2

dipole-dipole

Answer 2

forces arise from the attraction between the positive end of one polar molecule and the negative end of another.

Question 3

hydrogen bonds

Answer 3

strong dipole-dipole bonds

Question 4

order of bonds from weakest to strongest

Answer 4

london dispersion, dipole-dipole, hydrogen

Question 5

OH bonds

Answer 5

polar covalent bonds, between an oxygen atom and a hydrogen atom in a molecule.

Question 6

hydrophobic vs hydrophilic

Answer 6

hydrophobic repel water. non polar (oil, hexane)

hydrophilic-interact well with water, polar (water, alcohol, ect)

Question 7

polar

Answer 7

Unequal sharing of electrons, different electronegativity, asymmetrical shape.

Question 8

non polar

Answer 8

Equal sharing of electrons, similar electronegativity, symmetrical shape.

Question 9

what type of intermolecular attractions a particular molecule will be able to form based on its structure

Answer 9

By the molecular structure and the type of bonds , you can predict the attractions a molecule can form.

Question 10

what makes a molecule will be soluble in water based on its structure

Answer 10

polar or ionic are generally soluble in water
The ability to form hydrogen bonds with water causes solubility.
