Note: In the following questions a statement of Assertion (A) followed by a statementof Reason (R) is given. Choose the correct option out of the choices given below each question.
Assertion (A): Silicones are water repelling in nature.
Reason (R): Silicones are organosilicon polymers, which have (–R2SiO–) as repeating unit.
Silicones are made up of alkyl groups having general formula 
like 
which are non-polar in nature. Thus, they show water-repellent nature.
Silicones are organosilicon polymers, which have (–R2SiO–) as repeating unit. As they are made up of Silicon and Oxygen, therefore, they act as polar compound. So, they show hydrophilic nature.
Therefore, both assertion and reason are correct statements but reason is not correct explanation of assertion.
So, option (ii) is correct.
