Cyclohexanone tollens test
WebCyclic hemiacetals and hemiketals. Before we get into the discussion of cyclic hemiacetals and hemiacetals, let’s just quickly recollect how they are formed. They are formed when an alcohol oxygen atom adds to the carbonyl carbon of an aldehyde or a ketone. This happens through the nucleophilic attack of the hydroxyl group at the ... WebThe Tollens reagent oxidizes the aldehyde as fast as it is formed, so the equilibrium keeps getting pulled to the right (Le Châtelier's Principle) until eventually all the fructose is oxidized. 3 comments ( 8 votes) Upvote Downvote Flag more boram lee 8 years ago How can aldehyde be carboxylate anion?
