You know the oxidation reacts - primary alcohol ---> aldehyde/carboxyllic acid, secondary alcohol ---> ketone,

Well can phenol undergo this is as well?

No, phenol cannot be oxidized as the carbon atom to which the OH is attached has no Hydrogens linked to it. In this way it's similar to a tertiary alcohol.

Phenol is not really an alcohol as such, it could be better thought of as an enol, but that is undergraduate chemistry so all you need to know is it cannot be oxidised.

sorry, that's not quite right. Phenols CAN be oxidised by strong oxidising agents....http://www.chem.ucalgary.ca/courses/.../ch24-3-5.html

Probably best not to argue with a six year old thread, you might not get the replies you expect.

All the examples you linked to are for multiply substituted phenols. But does phenol (C6H5OH) carry out the same reactions?

Well so can tertiary alcohols and ketones if you combust them. I suppose you can oxidise most things, if you count combustion.
