The correct answer is (a). Buckminster fullerene is a form of carbon compound of clusters of 60 carbon atoms bonded together in polyhedral structure composed of pentagons or hexagons. It is also known as a buckyball or a fullerene. It was first discovered in 1985 by Harold Kroto, James R. Heath, Sean O’Brien, Robert Curl, and Richard Smalley. They were awarded the Nobel Prize in Chemistry in 1996 for their discovery.
Buckminster fullerene is a very stable molecule and is resistant to oxidation and heat. It is also a good conductor of electricity and heat. It has been used in a variety of applications, including electronics, medicine, and materials science.
(b) A polymer of fluorine is a long chain molecule made up of repeating units of fluorine atoms. Fluorine is a very reactive element and does not form polymers easily.
(c) An isotope of carbon heavier than C14 is a carbon atom with a different number of neutrons than carbon-14. Carbon-14 is a radioactive isotope of carbon with a half-life of 5,730 years. It is used in carbon dating to determine the age of organic materials.
(d) None of these is a correct answer.
