Vedclass · Answer

(C) Silicones are synthetic organosilicon polymers with the general formula $(R_2SiO)_n$. They have a backbone of alternating silicon and oxygen atoms with organic side groups attached to the silicon atoms. These organic groups (like alkyl groups) make the surface of silicones water-repellent or hydrophobic. Therefore,the Assertion is correct. However,the $Si-O-Si$ linkages in silicones are highly stable and are not moisture sensitive; in fact,they are resistant to water. Thus,the Reason is incorrect.

Assertion : Silicones are hydrophobic in nature.
Reason : $Si-O-Si$ linkages are moisture sensitive.
