Q1    Describe what you would expect to observe when ethene is reacted with bromine, write down both the structural formula of the product and the empirical formula of the product. Also write down the full structural formula of the isomer of the product.

CH₂  =  CH₂   +       Br₂           Br  --  CH₂ --  CH₂ --  Br

    ethene           Bromine          1,2- dibromoethane or ethylene bromide

Molecular formula of ethylene: C₂H₄Br₂

Structural formula of ethylene:

              H           H

                |             | 

H   ----    C   ----   C   ----   H
