    The chemical reaction important in rubber production is  - ProProfs

    The chemical reaction important in rubber production is 

    • Condensation

    • Polymerization

    • Oxidation

    • Reduction

    Correct Answer
    A. Polymerization
    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.

    Synthetic rubber can be gotten from the following except  - ProProfs

    Synthetic rubber can be gotten from the following except 

    • Styrene

    • Butadiene

    • Chloropene

    • Isoethylene

    Correct Answer
    A. Isoethylene
    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.

    The first synthetic rubber was discovered in  - ProProfs

    The first synthetic rubber was discovered in 

    • Hoffmann laboratory

    • Elberfied laboratory

    • Fritz laboratory

    • Bayer laboratory

    Correct Answer
    A. Bayer laboratory
    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.

    The first synthetic rubber discovered is  - ProProfs

    The first synthetic rubber discovered is 

    • Isoprene

    • Butadiene

    • Styrene

    • Polybutadeine

    Correct Answer
    A. Isoprene
    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.

    Synthetic oils raise fuel efficiency from 1.8 to  - ProProfs

    Synthetic oils raise fuel efficiency from 1.8 to 

    • 4%

    • 5%

    • 6%

    • 7%

    Correct Answer
    A. 5%
    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.

    Synthetic oil is used in the following except  - ProProfs

    Synthetic oil is used in the following except 

    • Aircraft jet engines

    • Metal stamping

    • Motor engine

    • Drilling engines

    Correct Answer
    A. Drilling engines
    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.

    Group III base oils are sometimes regarded as  - ProProfs

    Group III base oils are sometimes regarded as 

    • Fully synthetic

    • Molecularly synthetic

    • Mineral synthetics

    • Base synthetics

    Correct Answer
    A. Fully synthetic
    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.

    Which of these is not an advantage of synthetic motor oils? - ProProfs

    Which of these is not an advantage of synthetic motor oils?

    • Higher viscosity index

    • Decreased evaporative loss

    • Increased engine movement

    • Increased engine life

    Correct Answer
    A. Increased engine movement
    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.
