Unit 1: Intermolecular forces

Question 1

What are the three intermolecular forces?

Answer 1

hydrogen bond
vander waal
ionic

Question 2

Vander Waals bonding strength

Answer 2

weakest

Question 3

Vander Waals bonding is what type

Answer 3

Partial and induced

Question 4

What is Partial

Answer 4

sharing but hogging, whole charge not given away

Question 5

what is formal

Answer 5

whole electron taken/given

Question 6

what is induced

Answer 6

temperary

Question 7

what is permanent

Answer 7

always going to share

Question 8

Polar bonding is when

Answer 8

sharing electron but one element wants it more

Question 9

non polar bonding

Answer 9

elements share electron equally

Question 10

Weak vs really weak

Answer 10

weak- still holds shape

really weak, won’t hold shape

Question 11

Hydrogen bonding

Answer 11

is partial and permanent

Question 12

Ionic bonding is

Answer 12

permanent and formal

Question 13

it takes energy to ___ bonds

Answer 13

break

Question 14

Energy is released when you ____ Bonds

Answer 14

form

Question 15

Why/how do ionic bonds form

Answer 15

to fill valence shell

Ions, take/give electron to fill valence shell then when in water the water molecules separate and weaken the bond

Question 16

why/how does Vander waals bonds form

Answer 16

stronger together

push very close together electron movement in atoms start to sync

Question 17

why/how do hydrogen bonds form

Answer 17

the neg. charge pulls in that partial charge atoms

the neg. partial charges will attract the pos. partial charges,

Question 18

Non polar covalent bonds form in which bond

Answer 18

Vander Waals

Question 19

Polar covalent bonds form in which bonds

Answer 19

hydrogen

Question 20

Melting does what to bonds

Answer 20

breaks weak bonds

Question 21

Freezing does what to bonds

Answer 21

forms weak bonds

Question 22

Ionic bonds are associated with what

Answer 22

ions

Question 23

Hydrogen bonds are associated with what molecule

Answer 23

polar

Question 24

Van der Waal bonds are associated with what molecule

Answer 24

Non-polar
