Copper was discovered in North Africa.
C chemical since it is after all made of chemicals
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).
