Question

Determine the reagents needed and the synthetic intermediate that is formed in the conversion of the secondary alcohol into the cyanohydrin given below. drag the appropriate labels to their respective targets.

Answer 1

Secondary Alcohol is converted into corresponding Cyanohydrin in two steps;

Step 1:
Oxidation of Sec. Alcohol:
Secondary Alcohols when treated with Sodium Dichromate in acidic medium are converted into corresponding Ketone.

Step 2:
Reduction of Ketone using HCN:
Ketone is reduced to Cyaynohydrin when treated with CN nucleophile. A nucleophillic addition reaction takes place.
