The most stable form of carbon at high temperature is X. The C – C bond length in diamond is Y while C – C bond length in graphite is Z. What are X, Y and Z respectively ?
A.Graphite, 1.42 Å, 1.54 Å
B.Coke, 1.54 Å, 1.84 Å
C.Diamond, 1.54 Å, 1.42 Å✓ Correct
D.Fullerene, 1.54 Å, 1.54 Å
Explanation
Diamond have hybridisation 3 sp and graphite has 2 sp , so graphite has less bond length then diamond.
