C₆₀ Fullerene, Diamond, Graphite

Question 1

what shape molecule is C₆₀ Fullerene

Answer 1

sphere ( football shape)

Question 2

C₆₀Fullerene is made of what atoms

Answer 2

carbon

Question 3

how many carbon atoms are joined together in C₆₀Fullerene

Answer 3

60

Question 4

what structure does C₆₀Fullerene have

Answer 4

simple molecular structure

Question 5

can C₆₀Fullerene conduct electricity

Answer 5

NO

Question 6

C₆₀Fullerene has low melting points because

Answer 6

There are weak intermolecular forces and little energy is needed to overcome these forces

Question 7

diamond is what structure

Answer 7

GIANT covalent

Question 8

each carbon in diamond is bonded to how many other carbon atoms

Answer 8

4

Question 9

are there free electrons in diamond and why

Answer 9

NO because there are 4 bonds of carbon to each carbon

Question 10

properties of diamond (3)

Answer 10

• high melting point
• DOES NOT conduct electricity
• Is hard and dense

Question 11

what is diamond used for (2)

Answer 11

jewellery and cutting

Question 12

each carbon atom in graphite is bonded to how many other carbon atoms

Answer 12

3

Question 13

Graphite has a _______ structure

Answer 13

GIANT covalent

Question 14

what structure does graphite have

Answer 14

its in layers

Question 15

does graphite conduct electricity

Answer 15

yes

Question 16

why does graphite conduct electricity

Answer 16

because there is a delocalised electron that exists between the layers due to there only being 3 bonds for each carbon atom

the unpaired electron becomes delocalised

Question 17

graphite has ____ forces

Answer 17

weak intermolecular forces of attraction

Question 18

properties of graphite (3)

Answer 18

• conducts electricity
• high melting and boiling point
• soft and slippery ( layers can be moved)

Question 19

In C₆₀Fullerene, each carbon atom is bonded to how many others

Answer 19
