Question

Complete oxidation of ethanoic acid give what ?

Answer 1

Answer:

complete oxidation of ethanoic acid gives ethanol with carbon dioxide

Answer 2

Ethanol is an organic alcohol of molecular formula C2H5OH , and that of ethanoic acid is an organic carboxylic acid of molecular formula , CH3COOH.

So in order to convert to ethanol to ethanoic acid , we need to oxidise the alcohol and get the desired product.

This can be achieved by reacting the alcohol with a strong oxidising agent.

Step 1:—

CH3CH2OH + [O] → CH3CHO + H2O

Step 2:—

CH3CHO +[O] → CH3COOH

(Reaction takes place in presence of oxidizing agent K2Cr2O7 + Dil.H2SO4

K2Cr2O7 + 4H2SO4(Dil.) → K2SO4 +Cr(SO4)3 + 4H2O + 3[O]. )
