    Solution:

    2-Hydroxypropane will give CH3COCH3 which, in turn, will show iodoform test.

    CH3COR is oxidized by NaOI to form iodoform and RCO2Na

    wherein

    C6H5COCH3+NaOH+I2C6H5CO2Na+CHI3


    Acetamide and methyl acetate don't produce a yellow precipitate.

    However, acetophenone and 2-hydroxypropane will result in a yellow precipitate.
