JEE Advanced levelOne or more correct optionsDifficulty 3 of 3o1217

Which statements are correct?

  1. AN-methylacetamide reacts with ethanol at room temperature to give ethyl acetate
  2. B and at room temperature give methylammonium acetate rather than the amide
  3. C with 2 equiv of gives N-methylacetamide and methylammonium chloride
  4. Dstrong heating of methylammonium acetate gives N-methylacetamide and water

Answer: B, C, D

The amine is a base and the acid is an acid, so proton transfer is faster than attack on . At high temperature the salt dehydrates to the amide. The acid chloride aminolysis uses a second mole of amine for HCl. Amides do not undergo alcoholysis at room temperature.
