Question

Which of the following statements are strictly true regarding the reagents and conditions of the Iodoform test?

Answer: A,B,C

💡 Solution & Explanation

The reagent is $I_2/NaOH$ (or $NaOI$). The product is Iodoform ($CHI_3$), a distinct yellow crystalline solid. It distinguishes 2-pentanone (a methyl ketone, positive) from 3-pentanone (not a methyl ketone, negative). However, exhaustive halogenation requires 3 moles of $I_2$ to replace all 3 alpha-hydrogens, not one mole.
