I know that a ketone will result from a reaction of a 2 degree alcohol with PCC and that aldehyde will result from a reaction of 1st degreee alcohol with PCC. But will Ketone, or neither ketone/aldehyde result from a reaciton of a third degree alcohol with PCC? Why? Can someone explaing it to me... thanks

I'm not quite sure what "PCC" is, but I do know that it is necessary to have at least one hydrogen atom on the carbon atom holding the -OH group of an alcohol before it can be oxidides. Tertiary alcohols don't have this H atom, so only primary and secondary alcohols can be oxidised.

To the reference of previous responder, PCC is pyridinium chlorochromate, C5H5NH(+)CrO3Cl(–).
This reagent is quite selective to primary (1st degree is nothing but primary) and secondary alcohol.
For example, if you have a tertiary and a primary alcohol on the same compound, PCC oxidizes only the primary and not the tertiary alcohol.
Look at the source mentioned for reference:
