When c2h4 molecules polymerize, the name of the polymer formed is

Gnoma [55]

<span>When c2h4 molecules polymerize, the name of the polymer formed is (b) Polyethylene. This is because the compound C2H4 is ethylene (common name) or ethene (IUPAC name) and polymerizing it would produce polyethylene. The other names are not applicable for C2H4.
