The correct option is B CHCl3
When bleaching powder (CaOCl2) is distilled with acetone and water, chloroform is obtained.
CaOCl2+H2O→Ca(OH)2+Cl2
Cl2+H2O→2HCl+[O]
CH3COCH3+3Cl2→CCl3COCH3+3HCl
Chlorine is an oxidizing agent, as well as a chlorinating agent.
2CCl3COCH3+Ca(OH)2hydrolysis−−−−−−→2CHCl3+(CH3COO)2Ca
