WebMechanism of Iodoform Test. The entire process of the Iodoform reaction occurs in two steps. Step 1: First, hydroxide ions use acid to eliminate alpha hydrogen. As a result, the ion olate is formed. The iodide ion is then removed from the iodine molecule by the fused anion. This technique is repeated twice to produce R-CO-CI 3.
