Question

a
Assertion ?- Graphite is
good conductor
of
electricity, however Diamond belongs to the category of
insulator.
Reason: Graphite is soft in nature and
diamond is hard and brittle.
Assertion and reason​

Answer 1

Answer:

Graphite can conduct electricity because of the delocalised (free) electrons in its structure. ... However, in diamond, all 4 outer electrons on each carbon atom are used in covalent bonding, so there are no delocalised electrons. Hence both assertion and reason are correct but reason does not explains assertion.

Answer 2

Graphite is used in pencils and lubricants. It is a good conductor of heat and electricity. Its high conductivity makes it useful in electronic products such as electrodes, batteries, and solar panels.

Explanation:

a graphite molecule, one valence electron of each carbon atom remains free. ... Therefore, graphite is said to be a good conductor of electricity.
