what will you observe when ehane is passed into bromine in tetra chloromethane

Question

I was given this as a chemistry assignment and I am lost PLEASE HELP

Answer 1

If through a red-brown colored solution of bromine in CCl4 you bubble ethane gas, and there is a source of UV light to initiate the formation of bromine radicals, the radical reaction will begin and the red color of bromine will gradually disappear. The formation of colorless bromoethane will occur.
