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

The compound A forms B with sodium metal and again A forms C with PCl₅, but B and C form diethyl ether. Thus A, B and C are:

(1) C₂H₅OH, C₂H₅ONa , C₂H₅Cl

(2) C₂H₅OH, C₂H₅Cl, C₂H₅ONa

(3) C₂H₅OH, C₂H₅Cl, C₂H₄Cl₂

(4) C₂H₅OH, C₂H₅Cl, C₂H₅OC₂H₅

1. Grignard reaction

2. Raschig process

3. Wurtz-Fittig reaction

4. Friedel-Crafts reaction
