The alcohol and chromic acid produce a chromate ester, which then reductively eliminates the cr species. Oxidation of primary alcohols primary alcohols are easily oxidized just like secondary alcohols, and the initial product of oxidation is an aldehyde.
Like other alcohols, phenols undergo oxidation, but they give different types of products from those seen with aliphatic alcohols. For example, chromic acid oxidizes most phenols to conjugated 1,4-diketones called quinones. In the presence of oxygen in the air, many phenols slowly oxidize to give dark mixtures containing quinones.
