Chromic test
WebChromic Acid Test for Alcohols and Aldehydes Now, let’s have a look at this test for alcohols and aldehydes which involves this chemical (Oxidation Mechanism) Procedure: Three drops of the unknown compound to be tested are mixed with 5 drops of acetone and 5 drops of tetraoxochromic acid solution. Result: Webi) Chromic acid test is used to distinguish between aldehyde and ketone. It oxidizes aldehyde to acid but could not oxidize ketone. Therefore acetophenone being a ketone gives negative chromic acid test. … View the full answer Transcribed image text: Acetophenone gives what results in the following qualitative tests?
