Assertion: Silicones are hydrophobic in ...

Assertion: Silicones are hydrophobic in nature.
Reason: `Si-O-Si` linkage are moisture sensitive.

A

If both assertion and reason are true and the reason is the correct explanation of the assertion.

B

If both assertion and reason are true but reason is not the correct explanation of the assertion.

C

If assertion is true but reason is false.

D

If the assertion and reason both are false.

Text Solution

Verified by Experts

The correct Answer is:
C
Silicones are hydrophobic in nature because it is surrounded by bulky organic groups (alkyles). It is obtained in the form of oil, rubber or resins
`O - underset(underset(R)(|))overset(overset(R)(|))(Si)- O- underset(underset(R)(|))overset(overset(R)(|))(Si)- O- underset(underset(R)(|))overset(overset(R)(|))(Si)- O-`
so `Si- O- Si` linkages are moisture resistant not moisture sensitive
