How many of the following statements are correct regarding allotropes of carbon?
(a) Graphite is a good conductor of electricity along the layers.
(b) Diamond has a higher density than graphite.
(c) Buckminster fullerene contains 12 five-membered rings and 20 six-membered rings.
(d) The layers of graphite are 3.35 Å apart.
(e) Coke is the purest form of carbon.
(f) Fullerenes are molecular solids.
(g) Diamond is a good conductor of electricity.
Answer:
5
Solution:
Correct: (a), (b), (c), (d), (f) = 5. Anthracite (not coke) is the purest form, and diamond is a non-conductor of electricity - so (e) and (g) are wrong.
