Vitalism: A theory that an organic molecule cannot be produced from inorganic molecules, but instead can only be produced from a living organism or some part of a living organism. Vitalism suggested that an organic molecule such as urea cannot be synthesized solely from inorganic sources. Friedrich Wohler The German chemist Friedrich Wohler in attempted to make ammonium cyanate from silver cyanide and ammonium chloride and, in the process, accidentally made urea.
Ammonium cyanate is urea. India India ranks first in the number of organic farmers and ninth in terms of area under organic farming. Sikkim became the first state to become fully organic and other states including Tripura and Uttarakhand have set similar targets.
By the s, vitalism had been almost completely abandoned, not just because it had failed to convince practising biologists on a theoretical level but also on account of its inability to provide a basis for any experimental research programme, despite some interesting efforts in embryology by Driesch.

Through the nineteenth century and into the twentieth, experimental results brought to light much new knowledge about atoms, molecules, and molecular bonding. In it was Gilbert Lewis of U. Berkeley who described covalent bonding largely as we know it today electron-sharing. At about the same time, Sir Robert Robinson of Oxford University focused primarily on the electrons of atoms as the engines of molecular change.
Sir Christopher Ingold of University College, London, organized what was known of organic chemical reactions by arranging them in schemes we now know as mechanisms, in order to better understand the sequence of changes in a synthesis or reaction.
The field of organic chemistry is probably the most active and important field of chemistry at the moment, due to its extreme applicability to both biochemistry especially in the pharmaceutical industry and petrochemistry especially in the energy industry.
Organic chemistry has a relatively recent history, but it will have an enormously important future, affecting the lives of everyone around the world for many, many years to come. Skip to main content. Search for:.
