Question

difference between diamond and graphite​

Answer 1

Diamond and graphite can be differentiated from each other in the following manner.

Diamond

Graphite

It is the hardest substance known.

It is a soft  and brittle substance.

Carbon bonded to four different carbon atoms forming tetrahedron.

Each carbon atom is joined to three other carbon atoms by strong covalent bonds to form flat hexagonal rings.

Tetrahedrons combine to form 3-D structure.

Has 2-D layer-like structure in which atoms of a single crystal are arranged in a hexagonal ring in a single plane.

Does not conduct electricity

Good conductor of electricity

Answer 2

Answer:

Diamond:

• diamonds occurs naturally in free state
• diamond is transparent and has high refractive index 2.45
• Diamond occurs as tetrahedral crystals
• diamond is hardest natural substance ever known
• Diamond has high density 3.5 gram per ml
• diamond is insulator of heat and electricity
• Diamond burns in air at 900 degrees celsius to give CO2.

Graphite:

• graphite occurs naturally as well as manufactured artificially
• the fight is black in colour and opaque
• graphite occurs as hexagonal crystals
• graphite is soft and slippery in touch
• graphite has medium density 2.3 gram per ml
• the fight is a good conductor of heat and electricity
• graphite burns in air at 700 degree to 800 degree Celsius to give carbon dioxide
