Which of the following compound gives iodoform test?
CH3CN
CH3OH
CH3COCH3
C6H5OH
C.
CH3COCH3
Compounds containing CH3CO group give the iodoform test. The reaction is
CH3CO-CH3 + 3I2 +NaOH CHI3 + HCOONa + H2O
iodoform (yellow ppt)
Hence, only acetone gives the iodoform test.

A white ppt. of AgCl will form
NO2 will be evolved
CCl4 will dissolve in AgNO3
Nothing will happen
