Does acetamide respond positively to iodoform test?
From wikipedia article of haloform reaction:


  Acetyl chloride and acetamide don't give this (iodoform or in general haloform) test.


Why?


  Acetamide is not a ketone which is substantially more acidic than the
  amide.  It's about a million times too weak an acid at the alpha
  protons. Hydroxide is too weak a base. (Quora)
