Class 10 Science Chapter 4 Carbon and its Compounds

Carbon is one of the fundamental constituent elements in all living organisms. Some of the properties of Carbon includes:

  • The symbol of carbon is C and its atomic number is 6.
  • The atomic mass of carbon is 12.
  • Carbon takes four electrons to make a covalent bond.
  • Through catenation, Carbon can quickly form bonds with other atoms and give rise to large molecules.
  • Carbon bonds with hydrogen to form hydrocarbons which form the basis for organic chemistry,
  • Carbon constitutes the phenomenon of Allotropy.

Allotropes of Carbon: Allotropy is the phenomenon where two elements exist with two or more different physical states but similar chemical properties. Allotropes of carbon include Diamond, Graphite and Fullerene.

Classification of Carbon Compounds: Carbon compounds are classified into saturated and unsaturated carbon compounds.

  • Compounds formed by a single bond between two elements are called saturated compounds.
  • Compounds formed by double or triple bonds are unsaturated carbon compounds.
