Postlab Questions (2 pts ea; 8 pts total be specific and answer all in complete sentences): 1. How would you distinguish benzaldehyde and acetophenone by the results of their qualitative tests

Using the Iodoform test, we can differentiate both compounds.

Explanation:

Benzaldehyde (C6H5CHO -an aldehyde) and Acetophenone (C6H5COCH3 - a methyl ketone) can be differentiated by reacting both compounds with iodine in a basic (NaOH) solutions.

The methyl ketone (acetophenone) gives a pale yellow precipitate of triiodomethane (iodoform) while the aldehyde (benzaldehyde) would not react.

This is known as the IODOFORM test and is indicative for methyl ketones

the old alchemists made significant contributions to science even though there starting premises were off a bit. their conclusions after failure would steer them into better directions for investigation. science is no more than close observation and the initial mistakes result in rethinking and retrying experiments.
