WebApr 7, 2024 · This test can also be used to identify alcohols $(C{H_3}C{H_2}OH)$ . If the alcohol is a tertiary alcohol then it does not give yellow precipitate as it cannot be oxidised. If the alcohol is a primary alcohol then it must be ethanol (as this is oxidised to ethanal, which is the only aldehyde that gives a positive result with the iodoform test). WebThe iodoform test tests for the presence of a methyl ketone group (CH3-C=O). No carboxylic acids give a positive result, because they are carboxylic acids and not (methyl) ketones. So what does a negative test of iodoform look like, is there no change (remains yellow)? A negative test is when you don't get iodoform, so there's no change in ...
