Question 6

Electrons in an orbital have…

Answer 6

Opposite spins

Question 7

Why are giant molecules hard?

Answer 7

Rigid tetrahedral structure

Question 8

Why is graphite soft and slippery?

Answer 8

Weak London forces between layers

Question 9

Lattice meaning

Answer 9

Regular repeating structure (‘usually giant ionic lattice’)

Question 10

Why are giant ionic lattices brittle?

Answer 10

Any discolation leads to similar ions being adjacent, splitting the crystal

Question 11

Why can giant ionic structures dissolve in water?

Answer 11

Water is a polar solvent, which stabilises the seperated ions

Question 12

Dative covalent bond definition

Answer 12

Both of the shared electrons come from the same donor atom

Question 13

Electronegativity definition

Answer 13

The ability of an atom to attract the electron pair in a covalent bond to itself

Question 14

What are London forces?

Answer 14

Instantaneous dipole caused by fleeting moment of uneven distribution of electrons induces dipole in neighbouring molecule
–> temporary dipole induced dipole interaction

Question 15

For hydrogen bonding to occur, the __ needs to directly attached to __

Answer 15

For hydrogen bonding to occur, the H needs to directly attached to an N, F, or O

Question 16

What structure does ice have?

Answer 16

Open lattice tetrahedral structure
