Answers (1)
The assertion is true. Fullerenes are a type of allotrope of carbon, which means they are made up of pure carbon atoms arranged in a different structure than the usual diamond, graphite, or amorphous carbon. Fullerenes were discovered in 1985 by three scientists, Robert F. Curl Jr., Sir Harold W. Kroto, and Richard E. Smalley, for which they received the Nobel Prize in Chemistry in 1996.
The reason given to support the assertion is also true. Fullerenes are composed entirely of carbon atoms arranged in the form of a hollow sphere, tube, or ellipsoid. They have a unique structure, with a series of hexagonal and pentagonal rings that resemble a soccer ball or a geodesic dome. Fullerenes can also have additional structures, such as nanotubes and buckminsterfullerene.
Therefore, both the assertion and reason are correct, and the reason explains why the assertion is true.
