Although bucky ball is an allotropic form of carbon but it is included in organic chemistry?
Ans; Diamond and graphite are studied in inorganic chemistry while bucky ball is studied in organic chemistry due to the following properties of bucky ball,....
1.diamond and graphite are insoluble in in any organic solvent but bucky ball is sparingly soluble in many solvents. Common solvents for the fullerenes include aromatics, such as toluene, and others like carbon disulfide,. Fullerenes are the only known allotrope of carbon that can be dissolved in common solvents at room temperature.
2: bucky ball has degree of aromaticity. Buckminsterfullerene does not exhibit "superaromaticity": that is, the electrons in the hexagonal rings do not delocalize over the whole molecule. they have n pi bonding electrons free to delocalized . they try to delocalize the whole molecule and create aromatic characters,
3: Due to these aromatic character Fullerenes are stable, but not totally unreactive. It has some degree of angle strain which cause its reactivity.
4: The characteristic reaction of fullerenes is electrophilic addition. ... See MoreSee Less
