Step-by-step solution

Haloform reaction is shown by the compound having, Haloform reaction mechanism starts with the disproportionation of the halogen with the presence of the hydroxide ion. This gives the halide or the hypohalite. The hydroxide abstracts the proton, producing enolate. The hypohalite also reacts with any present methyl ketones, eventually forming a haloform.
