  • A
    Bayer-Villger rearrangement
  • Correct answer
    B
    Beckmann rearrangement
  • C
    Wolf-rearrangement
  • D
    Hoffmann reaction

Solution

The heating of oxime of acetone in presence of conc. H2SO4 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.
