Observe the following statements regarding \(\mathrm{C}_{60}\).
i. All carbons are \(s p^2\)-hybridised.
ii. It contains 12 rings of five carbons each and 20 rings of six carbons each.
iii. It is a non-aromatic compound.
iv. It is pure form of carbon.
v. \(\mathrm{C}-\mathrm{C}\) bond lengths in it are 143.5 and \(138.3 \mathrm{pm}\).
vi. It is prepared by heating graphite in an electric arc in the presence of oxygen.
The correct statements are
i, ii, iii, iv, v
i, ii, iv, v only
i, ii, iv, vi only
i, ii, iii only
Solution
In \(\mathrm{C}_{60}\), all carbon atoms are \(s p^2\)-hybridised. It contains 12 rings of five carbon each and 20 rings of six carbon each. It is anti-aromatic with spherically surrounded by \(\pi\)-electrons. It is a pure form of carbon. \(\mathrm{C}-\mathrm{C}\) bond length in it are 143.5 and \(138.3 \mathrm{pm}\). It is prepared by heating graphite in an electric arc under inert condition (He gas).
Thus, statements (i), (ii), (iv) and (v) are correct.
