Chromic acid and acetone reaction
Did you know?
Chromic acid is capable of oxidizing many kinds of organic compounds and many variations on this reagent have been developed: • Chromic acid in aqueous sulfuric acid and acetone is known as the Jones reagent, which will oxidize primary and secondary alcohols to carboxylic acids and ketones respectively, while rarely affecting unsaturated bonds. WebOnce H 2 CrO 4 is formed, its reactions are pretty straightforward: it converts primary alcohols (and aldehydes) to carboxylic acids and secondary alcohols to ketones. Is acetone a secondary alcohol? Secondary alcohols are oxidized to ketones.

WebChromic acid (H 2 CrO 4) reacts with alcohols to form a chromic ester in which the alcohol oxygen atom bridges the carbon and chromium atoms. The ester forms by nucleophilic … WebA new solvent system for PbI2 based on HI solution in acetone with a low boiling point is proposed. High solubility of PbI2 is caused by the formation of iodoplumbate complexes, and reaches a concentration of 1.6 M. Upon its crystallization metastable solvate phases PbI2∙HI∙n{(CH3)2CO} are formed. The latter allows for their easy deposition on …
