Which of the following compounds undergoes haloform reaction?
Options
- A( CH ₃ COCH ₃ )
- B( HCHO )
- C( CH ₃ CH ₂ Br )
- D( CH ₃- O - CH ₃ )
Correct answer
A. ( CH ₃ COCH ₃ )
Step-by-step solution
Compounds containing - 0 C - CH ₃ or - CH - CH ₃ group will give positive haloform test CH ₃ COCH ₃ contains - O C - CH ₃ group, therefore, it will give haloform reaction. The reaction involved is, CH ₃ COCH ₃+ I ₂+ NaOH CH ₃ COON a+ Yellowppt CH ₃ ^
