Chromic acid and primary alcohol
WebIn organic chemistry, dilute solutions of chromic acid can be used to oxidize primary or secondary alcohols to the corresponding aldehydes and ketones. Similarly, it can also be used to oxidize an aldehyde to its corresponding carboxylic acid. Tertiary alcohols and ketones are unaffected. WebPlace 0.5 mL of each of the following alcohols in separate test tubes: ethanol, 2-propanol, 1-butanol, 2-pentanol, 2-methyl-2-propanol, 1-octanol, and your unknown. 3. Add 1 mL of deionized water to each test tube. 4. Shake the contents of each tube well to see if they mix. Record whether each alcohol is soluble, insoluble, or slightly soluble ...

WebAlcohol Oxidation Reactions with PCC. PCC is a milder oxidizing agent than Chromic Acid. It will only oxidize a primary alcohol a single step to produce an aldehyde. This is the major difference in the alcohol oxidation reactions of PCC and Chromic Acid. And just like Chromic Acid, PCC will oxidize a secondary alcohol to a ketone.
WebJan 25, 2024 · Test for Alcohols: Alcohols are organic compounds with the functional group \ ( {\rm {–OH,}}\) called the hydroxyl group.
