WebAlkenes: Epoxide Reactions. Alkenes are capable of reacting with oxygen in the presence of elemental silver to form a series of cyclic ethers called epoxides. Epoxides are three‐atom … Webthe reaction: basic, neutral or acidic (Table 1). Associated with each condition is the mechanistic analysis which provides an idea of how the reaction takes place. For instance, if the alkylating agent is an electrophile in basic conditions, the mechanism shown in the first line in Scheme 2 is assumed to take place for a carboxylic acid.
WebOxidation Reactions of Sugars The oxidation of sugars provides energy in cellular respiration. Sugars are also the precursors to the other organic molecules in organisms. Stepwise oxidation of an alcohol function group in a sugar produces an aldehyde or ketone. An aldehyde can be oxidized to a carboxylic acid group.
