Amongst the following compounds, the one(s) which readily react with ethanolic KCN.
- A Ethyl chioride
- B Chiorobenzene
- C Benzaldehyde
- D Salicylic acid
Answer & Solution
Correct Answer
(C) Benzaldehyde
Step-by-step Solution
Detailed explanation
(a) Ethyl chioride gives ethyl cyanide, when it reacts with KCN (ethanolic). \[ \mathrm{C}_{2} \mathrm{H}_{5} \mathrm{Cl}+\mathrm{KCN} \stackrel{\text { EThande }}{\longrightarrow} mathrm{C}_{2}\mathrm{H}_{\mathrm{s}}-\mathrm{CN} \] (b) It does not react with KCN. (c)…
