CBSE Class 10 Science Chapter 4 - Carbon and its Compounds
Brief Information: In the previous chapter, we discuss compounds of importance to us. In this chapter, we will study some more interesting compounds and their properties. Also, we shall be learning about carbon, an element which is of immense significance to us in both its elemental form and in the combined form. Carbon is a versatile element that forms the basis for all living organisms and many of the things we use. Covalent bonds are formed by the sharing of electrons between two atoms so that both can achieve a completely filled outermost shell. Carbon forms covalent bonds with itself and other elements such as hydrogen, oxygen, sulphur, nitrogen and chlorine. Organic compounds are categorized into saturated and unsaturated carbon compounds. Saturated compounds are compounds with only a single bond. Unsaturated carbon compounds are compounds with a double or triple bond. The saturated compounds of carbon and hydrogen are methane, ethane, propane, butane, pentane and hexane.
The chapter also explains some of the chemical properties of carbon and its compounds such as combustion, oxidation, addition reaction, substitution reaction. Ethanol and ethanoic acid are carbon compounds of importance in our daily lives. Soap and detergents are studied with their chemical structures and properties and their difference is also discussed. Detergents are usually used to make shampoos and products for cleaning clothes.
