Question

Within the following lab,

Pour 2 ml of methyl alcohol in a test tube which is standing in a beaker of water. Heat a copper spiral wire to a red heat in the ugger part of the lab flame. On withdrawing the copper observe the black deposit of copper oxide. Immediately lower it into the test tube of methyl alcohol. Repeat if necessary until the pungent vapor of formaldehyde is evident.

CH3OH + O yields H-CHO + H2O

1.) What is the oxidizing agent in the preceding action? Also, How are aldehydes formed from alcohols?

Explanation / Answer

Cu + O ---> CuO (copper oxide)

this coppet oxide will act oxidising agent it will oxidise the methyl alcohol to formaldehyde

CH3OH + CuO ---> H-CHO + H2O

oxidising agent is CuO

this is a oxidation reaction

this will remove the two Hydrogens one is from oxygen attached hydrogen

another is from carbon attached hydrogen
