Chlorobenzene is prepared commercially by:

1. Grignard reaction

2. Raschig process

3. Wurtz-Fittig reaction

4. Friedel-Crafts reaction

A compound A of formula C₃H₆Cl₂ on reaction with alkali can give B of formula C₃H₆O or C of formula C₃H₄. B on oxidation gave a compound of the formula C₃H₆O₂. C with dilute H₂SO₄ containing Hg²⁺ ion gave D of formula C₃H₆O, which with bromine and NaOH gave the sodium salt of C₂H₄O₂. Then A is:

1. CH₃CH₂CHCl₂
2. CH₃CCl₂CH₃
3. CH₃CHClCH₂Cl
4. CH₂ClCH₂CH₂Cl
