### Step-by-Step Text Solution for Haloform Reaction **Step 1: Definition of Haloform Reaction** The haloform reaction is a chemical reaction in which a methyl ketone (or an aldehyde with a terminal methyl group) reacts with halogens (X2) in the presence of a base (usually NaOH) to produce a haloform (CHX3) and a carboxylate ion (RCOO-). **Step 2: Requirements for the Reaction** For a compound to undergo the haloform reaction, it must contain a methyl ketone group (COCH3) or can be converted to such a group through oxidation. This means that aldehydes or alcohols can also participate if they can be oxidized to form the necessary structure. ...
