A) Graphite is in powder form
B) Diamond has \[s{{p}^{2}}\] hybridization but graphite has \[s{{p}^{3}}\] hybridization.
C) Graphite is in planar form while diamond is in tetrahedral form
D) Graphite is covalent and diamond is ionic.
Correct Answer: C
Solution :
In diamond each carbon atom is \[s{{p}^{3}}\] hybridized and is joined to each other by strong covalent bond to form a tetrahedral structure. While in graphite carbon atoms form planar, hexagonal rings to give it a sheet like structure. Each sheet is joined to each other by weak van der Waal force. Hence diamond is harder than graphite.
