Answer» SOLUTION :Carbon exhibits many allotropicforms, both crystallins as well as amorphous. Diamond and graphite are two well known crystalline forms of carbon, third form of corbon known as fullerences. Fullerences are makde by heating of graphite in an electric are in the presence of inert gases such as helium or argon. The sooty material formed by condensation of vapourised `C^(a)` small molecular consists of mainly C60 with smaller quantity of C70 and traces of fallerence CONSISTING of EVEN number of carbon atoms upto 350 or above. |
