Answer» They key to the iodoform test is first being able to deprotonate hydrogens on a methyl group beta to a carbonyl group (this is possible because after deprotonation, the resulting negatively charged beta carbon will be in resonance with the carbonyl carbon). Formaldehyde has no beta hydrogens to deprotonate (both hydrogens are directly attached to the carbonyl carbon), so they will not deprotonate, and will therefore not undergo the iodoform test. |
