(a)
To determine: The two balanced equations that describe the given reactions that occur over and over again to produce a silicone
Interpretation: The two balanced equations that describe the given reactions that occur over and over again to produce a silicone polymer are to be stated.
Concept introduction: The repeated bonding of monomer units lead to the formation of polymer. They are mainly synthesized through condensation or addition reaction of monomer units.
(b)
To determine: An explanation corresponding to the fact that silicones are water repellent.
Interpretation: An explanation corresponding to the fact that silicones are water repellent is to be stated.
Concept introduction: The presence of alkyl or aryl group over atom provides hydrophobicity to the molecule. The long chain alkyl groups are hydrophobic in nature and repel water from the surface.
