CARBON AND ITS COMPOND ANANYA YADAV CARBON ◦ P;-6 ◦ E;-6 ◦ N;-6 ◦ Electronic configuration;(2,4) ◦ Valency-4 ◦ Hence, carbon is an tetravalent Imporatance of carbon 1.It is main element present in all living organisms 2.Mostly fuel are made with carbon 3.Other organic substances like carbohydrates , proteins ,alcohol , proteins , fats etc contain carbon 4. Plastic also contains carbon Bonds Ionic bond ◦Covalent bond This Photo by Unknown Author is licensed under CC BY-SA-NC This Photo by Unknown Author is licensed under CC BY-SA Covalent bond --Bond in which sharing of electrons takes place is known AS COVALENT BOND -Covalent bond as three types;1. Single bond 2. Double bond 3. Triple bond SINGLE bond This Photo by Unknown Author is licensed under CC BY-SA-NC This Photo by Unknown Author is licensed under CC BYSA This Photo by Unknown Author is licensed under CC BY-SA-NC Structure of methane • Covalent bounded molecules are senn to have strong bonds within the molecule. • But low melting and boliling point because of weak inter molecular forces. • Covalent compunds are usually poor conductors of electricity.

Catenation ◦ Property of bonding between atoms of same element for a long chain , branch , ring structure.

This Photo by Unknown Author is licensed under CC BY-SA-NC Isomerism ◦ Compounds which has same molecular formula but different structure is called isomers. ◦ And this property is known as isomerism This Photo by Unknown Author is licensed under CC BY-SA-NC Allotropes of carbon ◦ Different forms of element which have same chemical properties but different physical properties are known as allotropes ◦ Allotropes of carbon are diamond , graphite , fullerene. Diamond is a allotrope of carbon.Although it is made by covalent bond but it is strongest substance of nature and it has high melting point and it is also bad conductor of electricity. Diamond is used for making jewellery and also for cutting and drilling tools. This Photo by Unknown Author is licensed under CC BY-SA-NC 1.Diamond ◦ Graphite is made with weak van der wall forces. It is bounded with other three carbon atom to form a hexagonal rings ◦ Graphite is a good conductor of heat and electricity and it is slipery. ◦ Graphite is used as dry lubricant in machine parts and as leads of pencil.
