Web20 mrt. 2024 · Aldehydes, including aldoses, are oxidized to their respective carboxylic acids in the presence of $\ce{Br2}$ in $\ce{H2O}$.The reason this reaction is often discussed with carbohydrates is that it is useful for differentiating aldoses from from ketoses, which cannot be further oxidized.A solution of $\ce{Br2}$ and $\ce{H2O}$ will lose its characteristic …
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.
