According to my solution,ether was formed in place of C H X 2 O H in the end, whereas the answer says that C H X 2 O H group will remain unaffected. WebAcid-Catalysed Bromination of Ketones. Bromination of ketones occurs smoothly with bromine in acetic acid. The first step occurs in a cyclic way resulting in protonation of the carbonyl and formation of the enol …
WebCatalytic Hydration of Alkenes. In this reaction you end up adding water to your alkene. Since water is not nearly acidic enough to protonate the double bond of an alkene by itself, you’ll need a strong acid as a catalyst. You would typically see something like sulfuric acid (H 2 SO 4) as a catalyst in this reaction. WebCyclohexanone on being heated with NaOH solution forms: A B C D Hard Solution Verified by Toppr Correct option is C) The product obtained when cyclohexanone is heated with NaOH solution is as shown.

Weband ketones that have a-hydrogens. Notice that this reaction provides another method of form-ing carbon–carbon bonds. The base-catalyzed aldol addition involves an enolate ion as an intermediate. In this reac-tion, an enolate ion, formed by the reaction of acetaldehyde with aqueous NaOH, adds to a second molecule of acetaldehyde. Web39) When aldehydes are subjected to the same conditions that α-halogenate ketones (i.e., X2 and aqueous acid or base), they are: A) α-halogenated as well. B) reduced to alcohols. C) converted to the acid halide. D) oxidized to the acid or carboxylate. E) esterified. D
Web22 jan. 2024 · –CH3 on a methyl ketone is converted to a trihalomethyl group.
