4. \(\mathrm{CH}_3 \mathrm{CH}_2 \mathrm{CON}\left(\mathrm{CH}_3\right)_2 \xrightarrow[\text { Pyridine, } 70^{\circ} \mathrm{C}]{\stackrel{\mathrm{C}_6 \mathrm{H}_5 \mathrm{SO}_2 \mathrm{Cl}}{\longrightarrow}}\)
- A 1,3
- B 2,3
- C 3,4
- D 1,2
Answer & Solution
Correct Answer
(D) 1,2
Step-by-step Solution
Detailed explanation
\(1 . \mathrm{CH}_3 \mathrm{CH}_2 \mathrm{CH}=\mathrm{NOH} \xrightarrow[-2 \mathrm{CH}_3 \mathrm{COOH}]{\left(\mathrm{CH}_3 \mathrm{CO}\right)_2 \mathrm{O}} \underset{\text{(Ethyl cyanide)}}{\mathrm{CH}_3 \mathrm{CH}_2 \mathrm{CN}}\) So, reactions 1 and 2 give ethyl cyanide as…
