The term “rearrangement” is used to describe two different types of organic chemical reactions. A rearrangement may involve the one -step migration of an H atom or of a larger molecular fragment within a relatively short lived intermediate. On the other hand, a rearrangement may be a multi-step reaction that includes the migration of an H ...
Science of organic chemistry is about two hundred years old. Around the year 1780, chemists began to distinguish between organic compounds obtained from plants and animals and inorganic compounds prepared from mineral sources. Berzilius, a Swedish chemist proposed that a ‘vital force’ was responsible for the formation of organic compounds.
Organic Rearrangement Reactions refer to the vast class of chemical reactions which deal with chemical reactions whereby there is a change in the carbon structure of the molecule to make way for the isomer structure of the original molecule. It might be a single step reaction where there occurs the migration of the Hydrogen or H atom.

• Let us again divide the class into four groups – A, B, C and D. • Distribute the following samples to each group: − Few crystals of copper sulphate to group A. − One spatula full of copper sulphate to group B. − Chalk powder or wheat flour to group C. − Few drops of milk or ink to group D. • Each group should add the given
In a reaction, 5.3 g of sodium carbonate reacted with 6 g of ethanoic acid. The products were 2.2 g of carbon dioxide, 0.9 g water and 8.2 g of sodium ethanoate. Show that these observations are in agreement with the law of conservation of mass. sodium carbonate + ethanoic acid. → sodium ethanoate + carbon dioxide + water.
