under the conditions of oxidation
what does it mean when it states "heating the alcohol under reflux"...prefarably in simpl as level chemistry terms please
thank you again :)

reflux is to bring the distillate/gas back into the mixture.
in terms of alcohols it is means to return the aldehyde into the reactor to further oxidise it to a carboxylic acid.

The reactants (Including the alcohol) are placed in a round bottomed flask, which is mounted on an electric mantle, and held by a retort stand and clamps.
The end of a Leibig condenser is fitted, in a vertical position on to the neck of the reaction flask., the other end remaining open to the atmosphere. Cooling water is allowed to flow through the Leibig condenser from bottom to top. The electric mantle is switched on and the reactants allowed to react. The reactants may boil up into a vapour, which rises into the leibig condenser, whereupon the vapour cools and condenses back to a liquid and falls back into the reaction flask.
The idea of heating under reflux is so that all the components (reactants and products) are not lost. The rate of reaction can be controlled by the electric mantle, and the products can be separated later.

The answer is much less scientific. If the alcohol you are drinking is not getting you drunk enough, then you should simply drink something stronger, try poccine, thats like paint stripper, therefore never having to worry about refluxing it under oxidation.

This means that you heat the solution in a flask equipped with a condensor that keeps changing your evaporated alcohol back into liquid alcohol and dripping it back into the boiling flask.
The process in continue until you turn off the heat. You cool the condensor by running ice water through it so the hot alcohol vapor is condensed before is reaches the top of the condensor and is allowed to escape.
This is done to allow you to add heat to the reaction without losing the solvent of the reaction.

A reflux condenser is a vertical Liebig condenser that allows you to boil solutions without losing any material by evaporation.
