Ethene is bubbled through a solution of bromine in $CCl X_{4}$ . The red-brown colour disappears and the product formed is

A $CH X_{3} - CH X_{2} Br$
B $CH X_{2} = CHBr$
C $CH X_{3} - CHBr X_{2}$
D $BrCH X_{2} - CH X_{2} Br$

Answer: D

Bromine adds across the C=C bond (anti addition through a bromonium ion) so one Br goes on each carbon. The product is 1,2-dibromoethane, which is why the test decolourises bromine.
