19.3: Oxidation of Aldehydes and Ketones - Chemistry …
Alcohol oxidation is a class of organic reactions in which the alcohol functional group is converted into another functional group (e.g., aldehyde, ketone, carboxylic acid) in which carbon carries a higher oxidation state. Through a variety of mechanisms, the removal of a hydride equivalent converts a primary or secondary alcohol to an aldehyde or ketone, respectively. The ox… WebWhen an aldehyde or ketone reacts with a large excess of an alcohol in the presence of a trace of strong acid, an acetal is formed. An acetal is a compound in which two ether oxygens are bound to the same carbon. In other words, acetals are the ethers of carbonyl hydrates, or gem-diols (Sec. 19.7). (Acetals derived ウツボカズラ 酸性
