Upon reaction with CH ₃ MgBr followed by protonation, the compound that produces ethanol is

Options

  1. ACH ₃ CHO
  2. BHCHO
  3. CHCOOH
  4. D( CHO )₂

Correct answer

B. HCHO

Step-by-step solution

( CH ₃ CHO + CH ₃ MgBr CH ₃ CH ( OH ) CH ₃ ) ( HCHO + CH ₃ MgBr CH ₃ CH ₂ OH ) ( HCOOH + CH ₃ MgBr CH ₄ ) So ( HCHO ) on reaction with ( CH ₃ MgBr ) followed by protonation will produce ethanol.
