Question

define allotropes. name three allotropes of carbon

Answer 1

allotropes is a form of element whose chemical properties are same but physical properties are different
carbon - diamond, graphite , Buckminster fullerence

Answer 2

Different form of an element which have different physical appearance and properties but their chemical properties are same are called Allotropes.

There are three Allotropes of carbon:-

1. Diamond
2. Graphite
3. Fullerene

1. Diamond -
Diamond is a 3-dimensional network of strong carbon-carbon covalent bond.

2. Graphite -
In Graphite each carbon atom is bonded with three other carbon atoms to form hexagonal rings.


3. Fullerene -
It is as same structure as graphite. But also contain pentagonal or heptagonal rings. Spherical fullerene are called Bucky balls and Cyndrical fullerene are called lucky tube or nano tubes.
