Question

Which process does not occur during the formation of CHCl₃ from C₂H₅OH and bleaching powder?

Options

• Hydrolysis

• Oxidation

• Elimination

• Chlorination

Answer 1

Elimination

Expalantaion:

When ethanol (C₂H₅OH) reacts with bleaching powder (Ca(OCl)₂), it forms chloroform (CHCl₃) through a series of oxidation and chlorination reactions, followed by hydrolysis:

1. Ethanol is oxidized to acetaldehyde (CH₃CHO).
2. Acetaldehyde is chlorinated to trichloroacetaldehyde (CCl₃CHO).
3. Trichloroacetaldehyde undergoes hydrolysis to form chloroform (CHCl₃) and formic acid (HCOOH).
