Question

The heating of oxime of acetone in presence of conc. H2SO4 to form N-methyl ethanamide is called (A) Bayer-Villger rearrangement (B) Beckmann rearrangement (C) Wolf-rearrangement (D) Hoffmann reaction

Tardigrade Admin · Accepted Answer

The heating of oxime of acetone in presence of conc.

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.

Solution

Loss of

H_{2} O

occurs with simultaneous migration of the trans-R'.

Solution

Loss of H2O occurs with simultaneous migration of the trans-R'. Solution
