The given reaction involves reacting acetylene with Cl2 and excess AlCl3. The first step is the electrophilic attack on acetylene to form a vinyl cation (I), which then reacts with Cl2 to form 1,2-dichloroethylene (II). Further electrophilic attack on 1,2-dichloroethylene results in the formation of a new carbocation (III), which can be attacked by Cl- or C2H5Cl to form two possible products (IV). Therefore, the major products will be III and IV.
