However, in aldehydes it is positioned at the end of the carbon chain and in ketones it is positioned in the middle. As a result the first of each contains 3 carbons (prop-).

myweb.liu.eduThis test is selective for aldehydes. It is based on the fact that aldehydes are much easier to oxidize than ketones. In the Tollen’s test, the aldehyde reduces Ag+, complexed with ammonia, to Ag0 (metallic silver) while it is oxidized to a carboxylic acid. Ketones do not undergo this reaction. When the metallic Ag0 is produced it forms a
