WebWhen ethanol is warmed (60°C) with iodine in the presence of an alkali (NaOH, or Na 2 CO 3 ), iodoform is obtained. Step 1: NaOH + I 2 NaI + H 2 O. Step 2: Oxidation of ethanol to ethanal (acetaldehyde). Step 3: Ethanol so formed undergoes iodination. Step 4: Hydrolysis (cleavage) of Cl 3 CHO by alkali. Cl 3 CHO + NaOH + HCOONa. WebStep 1: First, an acid-base reaction. Hydroxide functions as a base and removes the acidic α -hydrogen, giving the enolate. Step 2: The nucleophilic enolate reacts with the iodine giving the halogenated ketone and an iodide ion. Step 3: Steps 1 and 2 repeat twice more yielding the trihalogenated ketone.
