2.4 molecular polarity

Question 1

2 polar molecules attract to each other

Answer 1

dipole-dipole interaction

Question 2

nonpolar molecules attract to each other

Answer 2

London dispersion

Question 3

strength of attracts (weakest)

Answer 3

nonpolaer to nonpolar

Question 4

london dispesion forces

Answer 4

between any 2 molecules

Question 5

dipole to dipole interaction

Answer 5

between any 2

Question 6

hydrogen bonds

Answer 6

between 2 very polar that contain N-H, O-H, F-H

Question 7

ionic bonds

Answer 7

between ions via transfer

Question 8

covalent bonds

Answer 8

between atoms in the same molecule; polar than nonpolar

Question 9

molecular polar

Answer 9

diametrically opposite must contain a polar covalent bond dipoles are asymmetrical meaning points in the same direction

Question 10

polar

Question 11

asymmetrical polar

Question 12

hydrophilic

Answer 12

water-loving

Question 13

cause of attraction between molecules of water

Answer 13

Their opposite charges

Question 14

hydrophobic

Answer 14

water hating

Question 15

what type of bond holds the hydrogen atoms to the oxygen atom within the water molecule

Answer 15

polar covalent

Question 16

why didn’t the chemicals mix together well?

Answer 16

because the nonpolar chemicals do not mix with the polar chemicals

Question 17

does the positive or negative atom have higher electronegativity?

Answer 17

negative

Question 18

if there is a small difference in electronegativity what is most likely its bond

Answer 18

polar covalent

Question 19

What there is a large difference in electronegativity

Answer 19

it’s ionic

Question 20

how could the polar bonds’s dipoles cancel each other out

Answer 20

if they are symmetrical it makes them nonpolar

Question 21

which atom has the most electronegativity

Answer 21

b

Question 22

which atom has the negative charge

Answer 22

b

Question 23

which atoms have the positive charges

Answer 23

a and c

Question 24

what changed in this model from the first

Answer 24

the bond dipoles flipped and the molecular dipole followed it, a and c are now negative, b is positive
