Which of the following undergoes Haloform reaction?
Options
- AHCHO
- BC ₂ H ₅ Cl
- C( CH ₃)₂ CO
- 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
