Question

In the following species, the one which is likely to be the intermediate during benzoin condensation of benzaldehyde, is (A)  (B)  (C)  (D)

Tardigrade Admin · Accepted Answer

When benzaldehyde is heated with aqueous ethanolic NaCN or KCN, it dimerises to form an α-hydroxy ketone called benzoin, and this reaction is formed as benzoin condensation. It involves self condensation of an aromatic aldehyde in the presence of CN -as catalyst. <img class="img-fluid question-image" alt="image" src="https://cdn.tardigrade.in/img/question/chemistry/adca511367f80ce1cf918b4fe087ff4a-.png" />

Q. In the following species, the one which is likely to be the intermediate during benzoin condensation of benzaldehyde, is

When benzaldehyde is heated with aqueous ethanolic $N a CN$ or $K CN$ , it dimerises to form an $α$ -hydroxy ketone called benzoin, and this reaction is formed as benzoin condensation. It involves self condensation of an aromatic aldehyde in the presence of $C N^{-}$ as catalyst.
