Question

19. Which of the following allotropic form of a Non-metal is a
good conductor of Electricity?
O a) Diamond
Ob) Graphite
O c) Coal
O d) Charcoal​

Answer 1

diamond

Explanation:

conductor is coal

Answer 2

Answer:

b) Graphite

Explanation:

Graphite is soft and slippery because there are only weak intermolecular forces between its layers. Graphite is a good conductor of heat and electricity.

2) Graphite can conduct electricity because of the delocalised (free) electrons in its structure.

3) These arise because each carbon atom is only bonded to 3 other carbon atomsHowever, in diamond, all 4 outer electrons on each carbon atom are used in covalent bonding, so there are no delocalised electrons.

4) These electrons in graphite are free to move through the structure.
