Question

Explain the difference in properties of diamond and graphite on the basis of their structure.

Answer 1

see the attachment for answer hope it helps u

Answer 2

Answer:

The difference between the properties of diamond and graphite are the following :

1. Diamonds are formed due to covalent bonds which forms a strong three-dimensional network whereas graphite are formed due Van der Waal force which is weak. Thus, Graphite are formed of flat carbon atoms layers one upon other. These carbon atoms layers slip over each giving graphite a soft nature. Whereas, the Diamond is very hard in nature.

2. Diamond have high density because of closely packed molecules whereas graphite has low density because of large spaces between molecules.

3. Diamond does not conduct electricity because carbon atoms are not free whereas graphite can conduct electricity very well because carbon atom is free and bonded to three carbon atoms leaving fourth valence electron free.
