The product of the reaction between ethanol and excess acidified K_{2Cr2O2 is}

Answer Details

The product of the reaction between ethanol and excess acidified K_{2Cr2O2 is ethanoic acid. The reaction is an oxidation reaction where ethanol is oxidized to ethanoic acid and K2Cr2O2 is reduced to Cr³⁺. The acidified K2Cr2O2 acts as an oxidizing agent and removes hydrogen from the ethanol molecule, producing ethanoic acid. Therefore, the correct answer is ethanoic acid.}
