Question

Silicones are ________. Select one: A. flat sheets of silicon and hydrogen atoms B. flat sheets of silicon atoms C. chains of alternating silicon and oxygen atoms with attached organic groups D. three-dimensional covalent networks of silicon atoms E. three-dimensional covalent networks of SiO4 tetrahedra

Answer 1

Option C. chains of alternating silicon and oxygen atoms with attached organic groups

Step-by-step explanation:

Silicones are polymers which comprises of repeating units of siloxanes i.e a chain of alternating silicon and oxygen atoms combined with an organic group which includes: carbon and hydrogen with other elements.

Answer 2

C. chains of alternating silicon and oxygen atoms with attached organic groups

Step-by-step explanation:

It contains Silicone-Oxygen backbone as found in Silicone Dioxide (silica) but it also has organic groups attached to this backbone with Carbon-Silicone attachments. This whole arrangement of Silicone, Oxygen and Attached organic groups make up Silicones.
