Question

Which of the following is not true about structure of diamond and graphite?

• A. In diamond, each carbon is $\mathrm { ps } ^ { 3 }$ s hybridized while in graphite each carbon is $\mathrm { sp } ^ { 2 }$ htybridised.
• B. In diamond, carbon atoms are closely packed in crystal lattice while graphite has layer structure.
• C. Diamond is a hard substance while graphite is a soft substance.
• D. Graphite is thermodynamically very less stable as compared to diamond and is amorphous from of carbon.

Answer 1

Answer: (D)

Graphite is thermodynamically very less stable as compared to diamond and is amorphous from of carbon.

Answer 2

: Graphite is thermodynamically more stable than diamond. It conducts heat and electricity due to movement of $\pi$ electrons between the layers. It is crystalline frome of carbon.
