Bonding

Question 1

Describe LDF

Answer 1

Weakest force of attraction between atoms and molecules

Only force between non polar and monatomic molecules

Question 2

Describe formation of temporary dipoles

Answer 2

One side of atoms has an excess in electrons (S-)
This excess attracts other atoms to have differing charges
This is the formation of LDF

Question 3

Describe Permanent Dipole interactions

Answer 3

Occurs between polar molecules

Stronger than LDF

Question 4

Describe hydrogen bonding

Answer 4

Strongest of the 3 intermolecular forces

H is bonded to N, O or F

Question 5

Describe how MP BP, solubility and viscosity can led to discovery of intermolecular bonding

Answer 5

High MP means hydrogen bonding
Differing electrons in non polar molecules is LDF

Polar and ionic substances dissolve in water

Question 6

True or false

Non polar molecules dissolve in non polar molecules and same with polar

Answer 6

True
