Which of the following reactions produce ethyl cyanide as a major product? 1. ( CH ₃ CH ₂ CH = NOH ( CH ₃ O )₂ O ) 2. ( CH ₃ CH ₂ Cl Ethanolic KCN ) 3. ( CH ₃ CH ₂ Cl Ethanolic KCN ) 4. ( CH ₃ CH ₂ CON ( CH ₃ )₂ [ Pyridine, 70^ C ] C ₆ H ₅ SO ₂ Cl )

Options

  1. A1,3
  2. B2,3
  3. C3,4
  4. D1,2

Correct answer

D. 1,2

Step-by-step solution

(1 . CH ₃ CH ₂ CH = NOH [-2 CH ₃ COOH ] ( CH ₃ CO )₂ O (Ethyl cyanide) CH ₃ CH ₂ CN ) So, reactions 1 and 2 give ethyl cyanide as the major product.
