NEET 2022 · ChemistryPrevious Year Question

Choose the correct statement:

Answer: (C) Diamond is $s p^{3}$ hybridised and graphite is $s p^{2}$ hybridised.. \textbf{Answer:} (C) Diamond is $s p^{3}$ hybridised and graphite is $s p^{2}$ hybridised.

A.Diamond and graphite have a two-dimensional network.
B.Diamond is covalent and graphite is ionic.
C.Diamond is $s p^{3}$ hybridised and graphite is $s p^{2}$ hybridised.✓
D.Both diamond and graphite are used as dry lubricants.

Correct Answer

Solution & Explanation

\textbf{Answer:} (C) Diamond is $s p^{3}$ hybridised and graphite is $s p^{2}$ hybridised. \textbf{Solution:} In diamond each carbon is $s p^{3}$ hybridised (3D tetrahedral network); in graphite each carbon is $s p^{2}$ hybridised (planar hexagonal sheets with delocalised pi electrons).
