When conducting the Schiff\'s Test on a suspected aldehyde or ketone, a student

Question

When conducting the Schiff's Test on a suspected aldehyde or ketone, a student expected to observe the purple color of a positive test. Rather than this happening, the student observed a color change to a light blue color in about 10 minutes. At first he was going to conclude that the test was negative but later realized that whereas aldehydes produce the purple color, ketones will react slower and produces the light blue color. Satisfied that he still had a positive test, although an unexpected one, he concluded that he was working with a ketone. Evaluate his reasoning.

Explanation / Answer

The compound may be a ketone but this is not a conclusive test. The student should perform a confirmatory test like a fehling's test.
