The organic materials become known according to their structure not according to their sources because most of the organic compounds which are prepared in laboratories are not formed in living organisms, The first organic compound that was prepared outside the living cells is urea Number of organic compounds are more than the number of inorganic compounds, Number of organic compounds are more than 10 million, while the number of inorganic compounds is about ½ million, so the ratio between organic and inorganic compounds is approximately 20: 1, Inorganic chemistry concerned with the other 111 elements or more. Homocyclic compounds are organic compounds in which all the corners of the ring have carbon atoms only, Heterocyclic compounds are organic compounds in which the corner of the ring have carbon atoms and other atoms of different elements. The abundance of organic compounds due to the ability of carbon atom to bind with itself or with others by several methods by single, double or triple covalent bonds forming straight chains, branched and unbranched chains or heterocyclic or homocyclic compounds. Not all compounds containing carbon atoms are considered organic compounds as carbon monoxide (CO), Carbon dioxide (CO 2), Carbonates (CO 3), bicarbonates (HCO 3), Cyanides (CN), Cyanates (CNO) & carbides, They are not considered as organic compounds because their properties are different from that of organic compounds. So, organic compounds can be prepared in industry, The failure of vital force theory to explain the formation of the organic compounds, because urea (an organic compounds) is prepared by heating an aqueous solution of ammonium chloride and silver cyanate (inorganic compounds). NH 4Cl (aq) + AgCNO (aq) → AgCl (s) + NH 4CNO (aq) Where ammonium cyanate is an inorganic compound while the Urea is an organic compound which is considered as a component of (urine of mammals), Since that time, Scientists have tried to synthesize organic substance in the lab, where these compounds are used widely in all fields of our life. Wohler destroyed the vital force theory, he performed an experiment which was considered to be the beginning of the end of Berzelius theory, Wohler was able to prepare Urea, which is organic compound by heating an aqueous solution of two inorganic compounds (Ammonium chloride and silver cyanate solution).
