Reaction with ag2o
WebA carboxylic acid first adds to the DCC molecule to form a good leaving group, which can then be displaced by an amine during nucleophilic substitution to form the corresponding amide. The reaction steps are shown below: Step 1: Deprotonation of the acid. Step 2: Nucleophilic attack by the carboxylate. Step 3: Nucleophilic attack by the amine. WebJan 23, 2024 · AgNO 3 + NaOH → AgOH + NaHO 3 2 AgOH → Ag 2 O + H 2 O Step 2: Aqueous ammonia is added drop-wise until the precipitated silver oxide completely dissolves. Ag 2 O + 4 NH 3 + H 2 O → 2 Ag ( NH 3) 2 + + 2 OH − Tollens’ reagent oxidizes an aldehyde into the corresponding carboxylic acid.

WebSep 25, 2024 · Reacting a hemiacetal with an alcohol and an acid catalyst produces an acetal in which the anomeric hydroxide has been replaced by an ether group. Monosaccharide acetal derivatives, called glycosides, are formed when a hemiacetal reacts with an alcohol in the presence of an acid catalyst. WebThe reaction that occurs using propanal (a safer alternative to ethanal) is: CH 3 CH 2 CHO(aq) + 2[Ag(NH 3) 2] + (aq) + 3OH – (aq) → 2Ag(s) + CH 3 CH 2 COO – (aq) + 4NH 3 (aq) + 2H 2 O(l) Find out more.
