Question

Silicones are:
(A) Conductors
(B) Insulators
(C) semiconductors
(D) Used to prepare graphite

Answer 1

Hint: We need to know about silicones. These concepts are covered in the chapter surface chemistry. Silicones are found in the p-block in the carbon family. They can be used as transistors.

Complete step by step answer:
We know that silicones are a type of synthetic polymer, a material made of smaller, repeating chemical units called monomers that are bonded together in long chains. Silicone consists of a silicon-oxygen backbone, consisting of hydrogen and/or hydrocarbon groups attached to the silicon atoms. These are the group of organic silicon polymers containing Si−O−Si linkages.
 Silicones are electrical insulators, inert, water repellent. There are Si units, so they can be used as semiconductors.
So, we need to select the correct answer.
The correct answer is C.

Note:
Silicones impart a number of benefits to the products in which they are used, including enhanced flexibility and moisture, heat, cold and ultraviolet radiation resistance. Silicones can be manufactured in many forms, including solids, liquids, semi-viscous pastes, greases, oils and rubber.
Silicone improves the efficiency, durability and performance of solar panels and photovoltaic devices, making them more cost-effective. Because they can withstand the sun for years, silicones are ideal materials for solar panel and photovoltaic applications.
It's used for medical, electrical, cooking, and other purposes. Because silicone is considered chemically stable, experts say it's safe to use and likely not toxic. The FDA has warned that injected liquid silicone may move throughout the body and can cause serious health consequences, including death.
Silicones have an exceptional breadth of chemical and physical properties. Silicones are flexible and resist moisture, chemicals, heat, cold and ultraviolet radiation. Products made with silicones take on these and other important properties so they are more stable, more aesthetically pleasing, easier to use or apply, and longer lasting.
