Question

What are allotropes?Sketch the structure of two allotropes of carbon namely graphite and diamond. Give two physical properties of them​

Answer 1

Answer:

Hope this helps you.

Explanation:

When an element possess two or more different forms in the same state, they are called allotropes and the phenomenon is known as allotropy. Diamond and graphite are the two allotropes of carbon.

DIAMOND:It has a crystalline structure.

                  It is made up of tetrahedral units.

GRAPHITE:It has a layered structure.

                  It has a planar geometry.

Answer 2

Answer:

Allotropes are two or more forms of the same element existing in the same physical state (either solid, liquid, or gas) that differ from each other in their physical, and sometimes also in chemical, properties.

Diamond:

• It has crystalline nature
• The geometry is tetrahedral.
• It has rigid covalent boning which is difficult to break.
• It is an electrical insulator.

Graphite:

• It has layered structure
• The geometry is planar
• It is soft. Its layers can be separated easily.
• It is good conductor of electricity.
