Final answer:
The linear polypropylene molecule segments indicate the molecule is a polymer, covalently bonded, and not an ionic compound. It is made of repeating monomer units linked together.
Step-by-step explanation:
The linear polypropylene molecule segments described indicate that the molecule is a polymer, which means it is a large molecule made up of many smaller molecules known as monomers that are covalently bonded in a repeating pattern. The statement that the molecule is a polymer is correct; saying it is a monomer is not, since a monomer is a single, smaller unit. The molecule is indeed a covalent compound because the monomers are linked together by covalent bonds. It is not an ionic compound since ionic compounds consist of ions bonded together by ionic bonds, which is not the case here.
Polymerization is the process by which monomers link together to form a polymer, either through an addition reaction, common in plastics like polypropylene and polyethylene, or a condensation reaction. Polypropylene itself is a versatile polymer used in various applications, such as plastic containers and clothing, and is known for its durability and flexibility.
