Question

Give reason why carbon exhibits allotropy

Answer 1

The property by virtue of which an element exists in more than one form in the same physical state, having same chemical properties but different physical properties is called allotropy. The different forms are called allotropes. For example, carbon has three common allotropes: diamond, graphite and fullerenes.

Some elements show allotropy due to the following reasons:

Firstly, the methods of formation or preparation of the element are different. Secondly, the arrangement of atoms in a given form changes according to its method of formation or preparation. Thirdly, the element has different energies in different forms. Lastly, the conditions like pressure, light and temperature are different at the time of formation or preparation of the element which gives rise to different forms

Answer 2

stable of network of covalent bonds and hexagonal rings is the reason that diamong is so strong .although graphite is the most stable allotrope of carbon under standard laboratory .allotropes are different structural forms of the same element and can exhibit quite different physical properties and chemical behaviours ...
