Carbon and it's Compounds

Introduction Carbon is an element which is of immense significance to us in both its elemental form and in the combined form. Bonding in Carbon - The Covalent Bond Although there are more than hundred elements around us we do not find these elements in their native form in nature. This is because most of these elements are highly reactive. Properties of Covalent Compounds A covalent bond can be formed in different ways. When a bond is formed by mutual sharing of one pair of electrons it is known as a 'single covalent bond', or simply 'a single bond'. Types of Covalent Bonds Types of covalent bonds are Single Bond, Double Bond , Triple Bond. Tetravalency in Carbon A carbon atom has a total of six electrons occupying the first two shells, i.e., the K-shell has two electrons and the L-shell has four electrons. Allotropes of Carbon The existence of one element in different forms, having different physical properties, but similar chemical properties is known as allotropy. Am
