  • Assertion (A): Silicons are water-repelling in nature. Reason (R): Silicons are organosilicon polymers, which have (–R_2SiO–) as repeating unit.

Assertion (A): Silicons are water-repelling in nature.

Reason (R): Silicons are organosilicon polymers, which have (-R_{2}SiO-) as repeating unit.

(i) A and R both are correct, and R is the correct explanation of A.

(ii) Both A and R are correct, but R is not the correct explanation of A.

(iii) A and R both are not true.

(iv) A is not true but R is true.

The answer is the option (ii) Both A and R are true, but R is not the correct explanation of A.

Silicones are hydrophobic and thus, are organosilicon polymers. So they neither react nor absorb water molecules.
