Question

The compound 1-Butene is modeled here.

Answer 1

Answer:

             Option-A. Covalent bonds would need to form between the molecules.

Explanation:

                   In given statement the molecules of 1-Butene are adding to each other forming a macromolecule called as Polybutene. Such type of reactions are called Polymerization reactions.

                   Polymerization reactions are those reactions in which small molecules called as monomers join together to form a large molecule also known as polymers. These reactions are done via different mechanisms like addition reaction, condensation reactions e.t.c.

Example:

              Polybutene (polymer) is made up of 1-butene (monomers) through addition reaction in which the double bonds of 1-butene molecules are involved in the formation of new single covalent bond via acid catalyzed, base catalyzed or free radical mechanisms.

                           n H₂C=CH-CH₂-CH₃    →    --[H₂C-CH(C₂H₅)]-n--

In above equation "n" represent large number, H₂C=CH-CH₂-CH₃ represent 1-Butene (monomer) and --[H₂C-CH(C₂H₅)]-n-- represent polybutene (polymer).
