Chromic acid test benzaldehyde

WebFor example, chromic acid (H 2CrO 4) or pyridinium chlorochromate (PCC, C 5H 5NH + ClCrO 3-), becomes reduced to Cr3+. Since chromic acid is not stable, it is made by the addition of CrO 3 to water. Either sulfuric or acetic acid is also added to act as a catalyst since the rate of oxidation of alcohols by chromic acid is much greater in an ...

WebOxygen being an electron rich species with a lone pair electron, can act as a good nucleophile. Typically, oxygen nucleophiles can be found in these compounds- water, hydroxides and alcohols. We are aware that carbon belongs to group IV and hence does not possess any lone pair of electrons. WebI would like to add that the purpose of the post is to be able to solve what the unknown compound is. The information that is given is the following: the unknown has melting point of 78-80 degrees celsius, tested positive for both the Tollens test and Chromic acid, tested negative for the iodoform test, and is insoluble in water.
