Final answer:
The polymer of polypropylene with randomly distributed methyl groups along the chain is atactic polypropylene. The correct answer is A.
Step-by-step explanation:
The polymer of polypropylene with the methyl groups randomly distributed along the chain is known as atactic polypropylene.
Different types of Polypropylene
There are three stereoisomers of polypropylene which are:
- Isotactic polypropylene - where methyl groups are oriented on the same side of the carbon chain.
- Syndiotactic polypropylene - where methyl groups alternate sides of the carbon chain.
- Atactic polypropylene - where methyl groups are placed randomly along the carbon chain.
- Copolypropylene - a copolymer of propylene with other monomers such as ethylene.
Given the options, atactic polypropylene is the correct answer as it best describes the arrangement of random methyl groups. Polypropylene is a versatile material used in various industries, often selected for its sturdiness and resistance to fatigue.
