tit? (How will you change Ethanol to Ethanoic Acid and Ethene?) 3 |
|
Answer» As ethanol is primary alcohol, so on oxidation of ethanol by nascent oxygen (obtained from K2Cr2O7+Dil.H2SO4) it forms aldehyde(acetaldehyde) first and then again on further oxidation by nascent oxygen it forms acetic acid or ethanoic acid (carboxylic acid). 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]. ) |
