Iodoform Test Simulator

Iodoform Test

Detects methyl ketones and specific alcohols via formation of Iodoform (CHI₃).

1. Setup Experiment

Select Unknown Compound

Acetone (Methyl Ketone) Ethanol (Oxidizable Primary Alcohol) 3-Pentanone (Non-Methyl Ketone) Methanol (Primary Alcohol)

2. Observation

Physical State Clear Liquid

Status: Standby.
Select an organic compound. The addition of Iodine (I₂) in Sodium Hydroxide (NaOH) will initiate the haloform reaction if the correct structure is present.

3. Chemical Principles

Positive Test: Requires a methyl group adjacent to a carbonyl carbon (CH₃-C=O), or an alcohol oxidizable to this structure (like CH₃-CH(OH)-R).

Mechanism:
1. Oxidation (if alcohol).
2. Tri-iodination of the alpha-methyl group.
3. Base cleavage to yield Iodoform (CHI₃↓) and a carboxylate salt.
