Question

The monomer units of silicons, a water repellant, acid resistant and heat resistant polymer, is:

• A. $Si$
• B. $Si{O}_2$
• C. $R_{2}Si(OH{)}_2$
• D. $RSiOH$

Answer 1

Answer: (C)

$R_{2}Si(OH{)}_2$

Alkyl group is water repellent and acid as well as heat resistant because of high bond energy.

Hence, the monomer units of silicones as water repellant, acid-resistant and heat resistant polymer is $R_{2}Si(OH{)}_2$.

Therefore, option C is correct.
