Exactly as before, as the cyanide ion approaches the slightly positive carbon atom, the lone pair of electrons is attracted towards the carbon and forms a bond with it. At the same time the two electrons in one of the bonds joining the carbon to the oxygen are repelled until they end up entirely ...
WebScope of Reaction. The order of reactivity of alcohols is 3° > 2° > 1° methyl. The order of reactivity of the hydrogen halides is HI > HBr > HCl (HF is generally unreactive). The reaction is acid catalyzed. Alcohols react with the strongly acidic hydrogen halides HCl, HBr, and HI, but they do not react with nonacidic NaCl, NaBr, or NaI. WebMECHANISM OF THE ALDOL REACTION. Step 1: First, an acid-base reaction. Hydroxide functions as a base and removes the acidic α-hydrogen giving the reactive enolate. Step 2: The nucleophilic enolate attacks the aldehyde at the electrophilic carbonyl C in a nucleophilic addition type process giving an intermediate alkoxide. Step 3:
WebThe addition of cyanide ion to the carbonyl group is another common reaction of aldehydes and ketones. The product of these reactions is a cyanohydrin.. It works in a slightly basic conditions since the HNC itself does not dissociate much to produce the – CN nucleophile in enough concentration:.
