The increasing order of rate of hcn addition
WebThe mechanism for the addition of HCN to propanone. In the first stage, there is a nucleophilic attack by the cyanide ion on the slightly positive carbon atom. The negative ion formed then picks up a hydrogen ion from somewhere - for example, from a hydrogen cyanide molecule. The hydrogen ion could also come from the water or the H 3 O + ions ...
