Finish the diagrams so that they display the electron energies in a carbon atom, a $\text{C}^+$ ion and a $\text{C}^-$ ion.
(b)
Buckminsterfullerene, $\text{C}_{60}$, is one of the simple molecular allotropes of carbon.
(b(i))[1]
State the hybridisation of the carbon atoms in $\text{C}_{60}$?
(b(ii))[1]
$\text{C}_{60}$ reacts with an excess of hydrogen to form a single product, $\text{C}_{60}\text{H}_x$. Using your answer to (i), suggest a suitable value for $x$.
(c)
Methylbenzene can take part in different reactions to give the products shown.
(c(i))[2]
Give the reagents and conditions for these two reactions. reaction 1 reaction 2
(c(ii))[1]
Name the mechanism of reaction 1.
(c(iii))[1]
Draw the structure of the product obtained if reaction 1 is carried out using an excess of chlorine.
