WebC C l X 3 is more electronwithdrawing than C H X 3. So 1 will exchange oxygen faster than 2. Presence of chloral hydrate indicates fast rate of oxygen exchange. … Chloral was first prepared, and named, by the German chemist Justus von Liebig in 1832. Liebig treated anhydrous ethanol with dry chlorine gas. Chloral is produced commercially by the chlorination of acetaldehyde in the presence of hydrochloric acid, producing chloral hydrate. Ethanol can also be used as a feedstock. This reaction is catalyzed by antimony trichloride:
