Carry out the transformations and name the substances C2H6-C2H5Br-C2H4Br2.

We write the reactions for the following chain: C2H6 -> C2H5Br -> C2H4Br2.
The first reaction takes place between ethane and bromine and looks like this:
C2H6 + Br2 -> C2H5Br + HBr
This reaction produces bromoethane and hydrogen bromide.
The second reaction takes place between bromoethane and bromine and looks like this:
C2H5Br + Br2 → C2H4Br2 + HBr ↑
This reaction produces dibromoethane and hydrogen bromide.
