Fullerenes Chemistry

Fullerenes are stable, but not absolutely unreactive. The sp2-hybridized carbon atoms, which are at their action minimum in collapsed graphite, accept to be angled to anatomy the bankrupt apple or tube, which produces angle strain.

The appropriate acknowledgment of fullerenes is electrophilic accession at 6,6-double bonds, which reduces angle ache by alteration sp2-hybridized carbons into sp3-hybridized ones.

The change in alloyed orbitals causes the bandage angles to abatement from about 120° in the sp2 orbitals to about 109.5° in the sp3 orbitals. This abatement in bandage angles allows for the bonds to angle beneath if closing the apple or tube, and thus, the atom becomes added stable.
