Matter is build up by atoms and these of subatomics particles: protons, neutrons and electrons. The atoms form bonds with their valence electrons. In organic compounds, the chemical bond is covalent, and because carbon can form chains, is possible a wide variety of organic compounds. Organic compounds contains others elements differents of carbon, like nitrogen, hydrogen and oxygen. Structure is important in Chemistry, because knowing structure of chemical compounds, is possible to obtain information on reactivity, and moreover, establish a relationship between structure and activity.
