Which one of the following forms propane nitrile as the major product?
- A Ethyl bromide + alcoholic KCN
- B Propyl bromide + alcoholic KCN
- C Propyl bromide \(+\) alcoholic AgCN
- D Ethyl bromide \(+\) alcoholic AgCN
Answer & Solution
Correct Answer
(A) Ethyl bromide + alcoholic KCN
Step-by-step Solution
Detailed explanation
When ethyl bromide reacts with alcoholic KCN, propane nitrile is obtained as main product.
\(\mathrm{C}_{2} \mathrm{H}_{5} \mathrm{Br}+\mathrm{Alc} . \mathrm{KCN} \longrightarrow \underset{\text { propane nitrile }}{\mathrm{C}_{2} \mathrm{H}_{5} \mathrm{CN}}\)
\(\mathrm{C}_{2} \mathrm{H}_{5} \mathrm{Br}+\mathrm{Alc} . \mathrm{KCN} \longrightarrow \underset{\text { propane nitrile }}{\mathrm{C}_{2} \mathrm{H}_{5} \mathrm{CN}}\)
