    1. CH3-CH2-(CHCl)-CH3 to CH3-(C=O)-(C=O)-CH3

    CH3-CH2-(CHCl)-CH3 ---NaOH---> CH3-CH2-CH(OH)-CH3 ---heat with conc. H2SO4 under reflux---> CH3-CH=CH-CH3 ---KMnO4/OH- ---> CH3-CH(OH)-CH(OH)-CH3 ---K2Cr2O7/H+ ---> CH3-(C=O)-(C=O)-CH3

    2. CH3-CH2-(CH2OH) to CH3-(C=O)-CH3

    CH3-CH2-(CH2OH) ---heat with conc. H2SO4 under reflux---> CH3-CH=CH2 ---HCl---> CH3-CHCl-CH3 ---NaOH---> CH3-CHOH-CH3 ---K2Cr2O7/H+ ---> CH3-(C=O)-CH3
