Question
How does acetone reacts with $ \text{HCN}$ and $NaHSO_3$ ?
✓
Answer
$(i)$ When acetone reacts with $ \text{HCN}$ it gives nucleophilic addition product acetone cyanohydrin. This reaction occurs slowly with pure $ \text{HCN}$ therefore this reaction is carried out in the presence of alkali.
