The addition compound obtained by treating propanone with hydrogen cyanide is:
The addition compound obtained by treating propanone with hydrogen cyanide is:
- A. propene cyanohydrin
- B. ethene cyanohydrin
- C. propane cyanohydrin
- D. ethane cyanohydrin
Step-by-step solution
Propanone (acetone) reacts with HCN via nucleophilic addition to form a cyanohydrin. The product has a three-carbon chain, so it is named as a derivative of propane, specifically propane cyanohydrin (common name: acetone cyanohydrin). The other options refer to compounds with different carbon chain lengths or unsaturation.
