Question
Assertion (A): Silicons are water repelling in nature.
Reason (R): Silicons are organosilicon polymers, which have (–R2SiO–) as repeating unit.
Options
A and R both are correct and R is the correct explanation of A.
Both A and R are correct but R is not the correct explanation of A.
A and R both are not true.
A is not true but R is true.
Solution
Both A and R are correct but R is not the correct explanation of A.
Explanation:
Silicones are organosilicon polymers and they are hydrophobic in nature. Silicones neither react nor absorb water molecules.
