Solution
Acetone undergoes haloform reaction with chlorine in the presence of alkali to form chloroform.
\[\ce{\underset{acetone}{CH3COCH3} + 3Cl2 + 4NaOH -> \underset{chloroform}{CHCl3} + CH3COONa + 3NaCl + 3H2O}\]
Acetone is halogenated at the methyl group to form trichloromethyl ketone, then it breaks down to give chloroform (CHCl3) and sodium acetate (CH3COONa).
