Which of the following compounds does not undergo haloform reaction?

Options

AEthanal
BPropanal
CPropanone
DButanone

Correct answer

B. Propanal

Step-by-step solution

Haloform reaction is given by acetaldehyde, all methyl ketones ( CH ₃- CO - R ) and all alcohols containing CH ₃( CHOH )- group. Propanal ( CH ₃ CH ₂ CHO ) does not have CH ₃ CO group and hence does not give haloform reaction. Thinking Hatke - Q. 31 This reaction can be used to distinguish methyl ketones ( CH ₃ CO - ) from ketones.
