Question

Which of the following is not an allotropic form of carbon?
A.Fluorine
B.Fullerene
C.Diamond
D.Graphite

Answer 1

Hint:We must remember that the carbon in general has \[3\] allotropic forms, allotropes are the different physical forms that exist in nature. Due to the valence of carbon which is capable of forming allotropes. Allotropes of carbon include nanotubes, nanobuds, and nanoribbons, ball shapes such as buckminsterfullerene and sheets such as graphane.

Complete step by step answer:

Let’s start with discussing a little about the allotropic forms of carbon. Carbon in general has \[3\] allotropic forms, allotropes are the different physical forms that exist in nature. All the three forms of carbon show different characteristics and all of this is due to the difference in the bonding between the carbon atoms.
The \[3\] Allotropes of carbon are Diamond, Graphite and Fullerene. The diamond is formed due to high pressure and is one of the hardest substances on earth. Graphite is seen by everyone in your pencils and this graphite is the only allotrope of carbon which is a good conductor of electricity. Fullerene is a football-like structure of carbon atoms.
Fluorine is a totally different atom when compared with carbon. Fluorine is having atomic number \[9\] whereas carbon is having atomic number \[6\].
Hence,
$\therefore $ The answer to this question is option A. Fluorine.

Note:
Carbons three allotropes are Fullerene, Diamond and Graphite which are very important forms of carbon and are used in many places. Graphite is used in pencil and used worldwide. As for diamond it is the strongest substance and when cut in the right way is used as a jewellery.
