Živojin Jocić
Živojin Jocić (6 October 1870 in Paraćin – 23 January 1914 in Belgrade) was a Serbian organic chemist. Jocić studied chemistry at the University of Petrograd in Imperial Russia. After his graduation in 1898, he stayed at the university and worked as an assistant. His teacher was Alexey Favorsky. In a relatively short time – between 1897 and 1911 – he published a large number of papers in organic chemistry, for the most part dealing with the synthesis of acetylene hydrocarbons and synthesis by means of Grignard reagent. He discovered the Jocic reaction, which involves nucleophilic displacement of the hydroxyl group in a 1,1,1-trichloro-2-hydroxyalkyl structure with concomitant conversion of the trichloromethyl portion to a carboxylic acid or similar functional group.

Functional Group
In organic chemistry, a functional group is any substituent or moiety (chemistry), moiety in a molecule that causes the molecule's characteristic chemical reactions. The same functional group will undergo the same or similar chemical reactions regardless of the rest of the molecule's composition. This enables systematic prediction of chemical reactions and behavior of chemical compounds and the design of chemical synthesis. The Reactivity (chemistry), reactivity of a functional group can be modified by other functional groups nearby. Functional group interconversion can be used in retrosynthetic analysis to plan organic synthesis. A functional group is a group of atoms in a molecule with distinctive Chemical property, chemical properties, regardless of the other atoms in the molecule. The atoms in a functional group are linked to each other and to the rest of the molecule by covalent bonds. For repeating units of polymers, functional groups attach to their Chemical polarity, nonp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
