Dear Mohini,

 Ethanol (ethyl alcohol) or propanone (acetone) when treated with bleaching powder gives chloroform. This reaction is known as haloform reaction.

  • From ethanol

The reaction occurs as the bleaching powder reacts with water giving chlorine and calcium hydroxide as:

laboratory method of chloroform preparation

The reaction proceeds in three steps:

First step is the oxidation of ethyl alcohol to give acetaldehyde.

First step is the oxidation of ethyl alcohol in haloform reaction

Second is chlorination of acetaldehyde to form chloral (trichloroethanal)

formation of chloral in haloform reaction

Best Of Luck...!!!!
