Propanal undergoes reaction with hydrogen cyanide to produce 2-hydroxybutanenitrile. Sodium cyanide is a suitable catalyst for this reaction. $\text{CH}_3\text{CH}_2\text{CHO} + \text{HCN} \rightleftharpoons \text{CH}_3\text{CH}_2\text{CH(OH)CN}$ Which statements concerning the reaction of propanal with hydrogen cyanide are correct?
- A1, 2 and 3 are correct
- B1 and 2 only are correct
- C2 and 3 only are correct
- D1 only is correct
