What do you think forms?

Here's the skeletal structure of glycerol.
Note how there are primary and secondary alcohols in glycerol which, under reflux, can be completely oxidised.

Yes, the primary alcohols will oxidise to carboxylic acids and the secondary alcohol will oxidise to a ketone (under reflux) :smile:
