Question

2) The reducing agent used for the reduction of copper oxide.
3) The product formed in the oxidation of ethyl alcohol.​

Answer 1

• Copper(II) oxide can be reduced by hydrogen

• The oxidations to remember are:
• primary alcohol →aldehyde →carboxylic acid;
• secondary alcohol→ketone →no further oxidation;tertiary alcohol →not oxidised.
• Ethanol is oxidised to produce ethanal by removing two hydrogen atoms.
• Ethanal is then oxidised to produce ethanoic acid, by adding an oxygen atom.
