The heating of oxime of acetone in presence of conc. H2SO4{H}_{2}S{O}_{4} to form N-methyl ethanamide is calledThe heating of oxime of acetone in presence of conc. H _ 2 S O _ 4 to form N-methyl ethanamide is calledThe heating of oxime of acetone in presence of conc. H _ 2 S O _ 4 to form N-methyl ethanamide is called

Options

  1. ABayer-Villger rearrangement
  2. BBeckmann rearrangement
  3. CWolf-rearrangement
  4. DHoffmann reaction

Correct answer

B. Beckmann rearrangement

Step-by-step solution

The heating of oxime of acetone in presence of conc. H2SO4{H}_{2}S{O}_{4} to form N-methyl ethanamide is called Beckmann rearrangement. In Beckmann rearrangement, R-migrates from carbon to nitrogen of an oxime to form N-substituted amide.
The heating of oxime of acetone in presence of conc. H _ 2 S O _ 4 to form N-methyl ethanamide is called
Loss of H2O{H}_{2}O occurs with simultaneous migration of the trans-R'.
