Abstract Oxidation was found for primary alcohol. When 6 drops of potassium dichromate and 1 drop of concentrated sulfuric acid were added to 1-pentanol‚ the color of 1-pentaol turned into dark green. In second experiment‚ precipitation was found when 6 drops of 2‚4-dinitrophenylhydrazine were added to both 5 drops of benzaldehyde and 5 drops of acetophenone. Based on these data‚ it is possible to find alcohol by oxidation and aldehyde by observing precipitation Introduction This experiments
