RankGuru · Accepted Answer

The **Haloform Reaction** identifies compounds containing the **$CH_3-CO-$ (Acetyl)** group or those that can be oxidized to it ($CH_3-CH(OH)-$ group).
1. **Methyl Ketones**: $R-CO-CH_3$ reacts with $X_2/NaOH$ to give $CHX_3$ (Haloform).
2. **Ethanol and 2-Alcohols**: $CH_3CH_2OH$ and $R-CH(OH)CH_3$ are oxidized by the halogen reagent to acetaldehyde/methyl ketone and then undergo the reaction.
- **Iodoform Test ($I_2, NaOH$)**: Gives a characteristic yellow precipitate of $CHI_3$. It is a primary test in JEE organic chemistry.
