Assertion (A) : Silicons are water repelling in nature. Reason (R ) : Silicons are organosilicon polymers, which have `(-R_(2)SiO-)` as repeating unit.
A
A and R both are correct R is the correct explanation of A
B
Both A and R are correct but R is not the correct explanation of A
C
A and R both are correct
D
A is not correct but R is correct
Text Solution
Verified by Experts
The correct Answer is:
b
Silicones are a groups of organo silicon polymers which have `(R_(2)SiO)` as a repeating unit. This suggests that silicones are surrounded by non-polar alkyl groups that are water repelling in nature. They have wide applications. It is used for water proofing of fabrics.
