Which of the following undergoes Haloform reaction?

Options

  1. AHCHO
  2. BC ₂ H ₅ Cl
  3. C( CH ₃)₂ CO
  4. DCH ₃ -O-CH ₃

Correct answer

C. ( CH ₃)₂ CO

Step-by-step solution

The haloform reaction is given by compounds containing a methyl ketone group ( CH ₃ -CO- ) or compounds that can be oxidized to this group, such as alcohols containing the CH ₃ -CH(OH)- group. Among the given options, ( CH ₃)₂ CO (acetone) contains the CH ₃ -CO- group and therefore gives a positive haloform test. HCHO (formaldehyde) lacks the CH ₃ -CO- group. C ₂ H ₅ Cl and CH ₃ -O-CH ₃ do not possess the required structural features to undergo the haloform reaction. Answer: ( CH ₃)₂ CO
