(C) The preparation of chloroform $(CHCl_3)$ from ethanol $(C_2H_5OH)$ and bleaching powder $(CaOCl_2)$ involves the following steps:$1$. Bleaching powder reacts with water to produce calcium hydroxide and chlorine gas: $CaOCl_2 + H_2O 	o Ca(OH)_2 + Cl_2$.$2$. Chlorine acts as an oxidizing agent to oxidize ethanol to acetaldehyde,and then as a chlorinating agent to form chloral $(CCl_3CHO)$.$3$. Calcium hydroxide then reacts with chloral to produce chloroform: $2CCl_3CHO + Ca(OH)_2 	o 2CHCl_3 + (HCOO)_2Ca$.Thus,bleaching powder provides both $Ca(OH)_2$ and $Cl_2$ for the reaction.

In the preparation of $CHCl_3$ from ethanol and bleaching powder,the latter provides:
