Q82 / 200 · NEET 2022 (Phase 1) · Chemistry

Choose the correct statement:

A
Diamond is covalent and graphite is ionic.
Correct answer
B
Diamond is ${sp}^{3}$ hybridised and graphite is ${sp}^{2}$ hybridized.
C
Both diamond and graphite are used as dry lubricants.
D
Diamond and graphite have two dimensional network.

Solution

Both diamond and graphite are covalent. Diamond is

{sp}^{3}

hybridised and has

3 - D

network. Graphite is

{sp}^{2}

hybridised and has planar structure Only Graphite is used as dry lubricants.

Hence, the correct answer is option: 'B'.
