Do You Know Synthetic Rubber And Synthetic Oil?

Explanation
Synthetic rubber is commonly used in the manufacturing of tires, hoses, and belts due to its durability, flexibility, and resistance to wear and tear. However, buttons are typically made from materials such as plastic, metal, or natural materials like wood, and do not require the specific properties provided by synthetic rubber. Therefore, buttons are not made using synthetic rubber.

Explanation
Isoprene is the correct answer because it was the first synthetic rubber to be discovered. Isoprene is a monomer that can be polymerized to form synthetic rubber. It was first synthesized in 1860 by chemist Charles Goodyear, who found that it could be vulcanized to create a durable and elastic material similar to natural rubber. Isoprene has since been used in the production of various rubber products, including tires, belts, and hoses.

Explanation
Bayer laboratory is the correct answer because the first synthetic rubber was indeed discovered there. In 1909, Fritz Hofmann, a chemist at the Bayer laboratory in Germany, successfully synthesized the first commercially viable synthetic rubber, known as Buna rubber. This discovery revolutionized the rubber industry and provided an alternative to natural rubber, which was in high demand but limited in supply. The development of synthetic rubber had a significant impact on various industries, including automotive, aviation, and manufacturing.

Explanation
Polymerization is the correct answer because it is the chemical reaction that is crucial in rubber production. Polymerization involves the joining together of monomers to form a polymer chain, which is the basic structure of rubber. This reaction allows for the formation of long, flexible chains of rubber molecules, giving rubber its unique properties such as elasticity and resilience. Condensation, oxidation, and reduction are not the primary reactions involved in rubber production and do not play as significant a role as polymerization.

Explanation
Synthetic rubber can be obtained from styrene, butadiene, and chloroprene. Isoethylene, on the other hand, is not a source of synthetic rubber. Isoethylene is a compound used in the production of polyethylene, which is a type of plastic, not rubber. Therefore, the correct answer is Isoethylene.

Explanation
Synthetic oil is not used in drilling engines. This is because drilling engines typically operate in harsh and extreme conditions, such as high temperatures and pressures, which require specialized lubricants with specific properties. Synthetic oils may not possess the necessary characteristics to withstand these conditions, making them unsuitable for use in drilling engines. However, synthetic oil is commonly used in aircraft jet engines, motor engines, and metal stamping applications due to its superior lubricating properties and ability to withstand high temperatures.

Explanation
Increased engine movement is not an advantage of synthetic motor oils. Synthetic motor oils are known for their higher viscosity index, which means they maintain their viscosity better across a wider range of temperatures. They also have decreased evaporative loss, which means they do not evaporate as quickly as conventional motor oils. Additionally, synthetic motor oils are known to increase engine life by providing better lubrication and reducing wear and tear. However, increased engine movement is not a recognized advantage of synthetic motor oils.

Explanation
Group III base oils are sometimes regarded as fully synthetic because they undergo a severe refining process called hydrocracking, which removes impurities and saturates the molecules. This results in a base oil with a higher viscosity index and improved performance compared to conventional mineral oils. Although they are derived from crude oil, the extensive refining process transforms them into a product that is considered fully synthetic in terms of performance and quality.

Explanation
Synthetic oils can increase fuel efficiency by 5%. This means that when synthetic oils are used instead of conventional oils, there is a 5% improvement in the amount of fuel consumed by the vehicle. This improvement in fuel efficiency can be attributed to the superior lubricating properties of synthetic oils, which reduce friction and allow the engine to operate more efficiently.
