(1) Propanone is a colourless liquid and has a fragrant smell. Its boiling point is 329 K and it is very much soluble in water.


(2) Propanone gives propan-2-ol on reduction with reducing agent like Sodium borohydride (NaBH4) or Lithium aluminium hydride (LiAlH4).


CH3COCH3 CH3-CHOH-CH3


(3) Ethanoic acid is obtained by oxidation of propanone, with alkaline potassium permanganate.


CH3COCH3 CH3COOH + CO2 + H2O


(4) On addition of HCN to propanone, it gives propanone cyanohydrin.


CH3COCH3 + HCN → CH3-COHCN-CH3
