Question

The purest form of carbon is:
a.) Graphite
b.) Diamond
c.) Lonsdaleite
d.) Fullerene

Answer 1

Hint: In order to solve this problem first we will elaborate the carbon element further then we will discuss its property and its types, on the basis of it we will find our required answer.
Complete step-by-step answer:
Carbon forms a huge number of compounds with a large number of elements. It is the only atom that has a high combining capacity to form compounds and molecules with other atoms and elements.
Diamond is the purest source of carbon. In the year 1955, graphite was first converted to diamond in the presence of catalysts such as copper, cobalt, chromium or manganese. Diamond is considered the purest type of carbon, since the diamond's structure is homogeneous and stable overall.
Diamonds are purer than graphite as the diamond carbon atoms are more closely bound than in graphite as a result of which impurities have trouble entering the diamond lattice. A 100 % pure diamond will be clear while impurity diamonds are mostly colored blue or yellow.
Hence, the purest form of carbon is diamond.
So, the correct answer is option B.


Note- Other elements do contain carbon atoms in their structure. Those are the only Carbon types. They're called allotropes. The geometric structure of the carbon atoms makes them vary. All of these materials are 100 % pure but they typically contain small quantities of impurities. The primary carbon allotropes are graphite and diamond. Allotropes are recently found in fullerenes and nanotubes.
