Carbohydrates
What are Carbohydrates? It is defined as polyhydroxy (more than one hydroxy group) aldehydes or ketones compounds produced on hydrolysis, which are called carbohydrates. The name carbohydrates means ‘hydrates of carbon‘. They are the most abundant organic molecules in nature. They are composed of Carbon, Hydrogen, and Oxygen. The empirical formula of carbohydrates is [CH2O]n However,…
Cannizzaro Reaction
Those carbonyl compound which donot contain α-H react in the presence of conc. base gives alcohol ( reduced product) and acidic salt (oxidized Product). Reaction of cannizzaro: Cannizzaro Reaction Mechanism: Step(01) formation of dianion: In this reaction , we use typical base OH which react on less hindered product because our preference is to make…
Pinacole-pinacolone rearrangement
An Acid catalyzed rearrangement in which 1,2-diol or pinacole is converted to carbonyl compound is called pinacole- pinacolone rearrangement. Pinacole : 2,3- dimethyl butane-2,3-diol Pinacolone :3,3-dimethyl-2- butanone Reaction of Pinacole-pinacolone rearrangement: Mechanism of pinacole-pinacolone rearrangement: Mechanism of pinacole-pinacolone rearrangement takes place in four steps Step(01): In this step hydroxyl group of pinacole is protonated by…

Chemical Bonding
The attractive force which holds various constituents (atoms, ions, etc.) together and stabilises them by the overall loss of energy is known as chemical bonding. Valence electrons play a fundamental role in chemical bonding. In the electron configuration of an atom, the outermost shell is called the valence shell, and the electrons in the valence shell (outermost…
Beckmann Rearrangement
“The acid-induced reaction that converts oxime to amide is called Beckmann rearrangement” In the Beckmann rearrangement, migration of the group does not depend upon migration aptitude but depends upon the orientation of the group related to a hydroxyl group. In…
