Why are aldehydes easily oxidized?

An
Explanation:
When we oxidize a primary alcohol, it is often very difficult to stop at the aldehyde stage, i.e.
The oxidation numbers of the ipso carbon from left to right, are
I once had a colleague with brilliant hands at these sorts of oxidations. He was good, he was quick, and he used to do all these oxidations with chromic acid. He assessed the stage of the reaction by thin layer chromatography, and he could invariably stop at the aldehyde. His professor (very unfairly!) complained that his results were not reproducible, but that's an old cop-out. He could reproduce his results; his successors had to work hard to emulate him.
