Polymerization of C4H6Cl2 isomers requires identifying compatible chain sequences

Steps:

• Identify the three isomers of C4H6Cl2: likely 1,2-dichloro-3-butene, 3,4-dichloro-1-butene, and 1,4-dichloro-2-butene based on standard organic chemistry.
• Recognize polymerization occurs via radical or coordination mechanisms on vinyl groups, forming head-to-tail or head-to-head linkages.
• Determine sequences in chains: mixed isomers allow random incorporation, producing specific diad or triad patterns.
• Select option showing valid repeating units from isomer connectivity.
