Assalam o Alaikum in this lecture i am going to discuss the reaction mechanism of the Jones Reagent which is used to oxidized primary alcohols into carboxylic acids and secondary alcohols into ketones. The jones reagent is composed of Chromium Trioxide CrO3, H2O, and H2SO4 (Sulfuric acid) which generates chromic acid H2CrO4. Oxidation of primary alcohols first generates an aldehyde which converts to the geminal / gem diol hydrate form which is then oxidized into a carboxylic acid. Tertiary alcohols are resistant to oxidation.This lecture is delivered in Urdu ,Hindi and English. 1° Alcohols are oxidized to carboxylic acids (RCOOH) under harsher reaction conditions: Na2Cr2O7, K2Cr2O7, or CrO3 in the presence of H2O and H2SO4. The mechanism for the oxidation of 1° alcohols to aldehydes parallels the oxidation of 2° alcohols to ketones detailed is discussed in this lecture. Oxidation of a 1o alcohol to a carboxylic acid requires three operations: oxidation first to the aldehyde, reac
