Propanone react with hcn

WebIt is used as a surrogate in place of HCN, as illustrated by its use as a precursor to lithium cyanide: (CH 3) 2 C(OH)CN + LiH → (CH 3) 2 CO + LiCN + H 2. In transhydrocyanation, an equivalent of HCN is transferred from acetone cyanohydrin to another acceptor, with acetone as byproduct. The transfer is an equilibrium process, initiated by base. WebGive the reagents and conditions for the first reaction. (la) In the second reaction, propanone undergoes an addition reaction with HCN in the presence of CN ions. Explain why this reaction would not take place at either a very low or very high pH. (c) Explain why it is necessary to use HCN and KCN in this reaction, rather than HCN on its own.
