Web-For the chromic acid test, my unknown #4 remained an orange-red color with no precipitate, the Acetone test tube also remained an orange red color. Given that this reagentreacts only with Aldehydes and primary and secondary alcohols, supports the idea that my unknown #4 is a methyl ketone and most likely Acetone. 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 …

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. Webpermanganate and then 1.0 mL of concentrated sulfuric acid is added while stirring. A strong exothermic reaction occurs. The sample is then treated with 2 mL concentrated nitric acid. 10 mL of concentrated HCl is added and the sample is heated until the reaction is complete and is then filtered. The filter is washed with hot concentrated HCl. cystic malformation
