Question

Which of the following substances would undergo the haloform reaction?

(a) CH₃COCH₃        (b) Acetophenone  (c) CH₃CH₂CHO

(d) CH₃CO₂H           (e) ${\mathbf{CH}}_{\mathbf{3}}\mathbf{C}\mathbf{\equiv }\mathbf{N}$

Step-by-Step Solution

Answer

The Compound (c), (d), and (e) will not undergo haloform reaction because they does not have methyl ketone group. Compound (a) and (b) will undergo haloform reaction.

Step 1: Determination of compound that will undergo Haloform reaction

Haloform reaction is used in the analysis to indicate the presence of methyl ketone group in the compound.

The Compound (c), (d), and (e) will not undergo haloform reaction because they does not have methyl ketone group.

Hence, Compound (a) and (b) will undergo haloform reaction.

Step 2: Haloform reaction for compound (a) and (b)

The haloform reaction for the compound (a) and (b) is as follows,
