Among the following substituted silanes the one which will give rise to cross linked silicone polymer on hydrolysis is
Options
- AR 3 S i C l
- BR 4 S i
- CR S i C l 3
- DR 2 S i C l 2
Correct answer
C. R S i C l 3
Step-by-step solution
It is trichloro alkyl silane which hydrolysed to R S i ( O H ) 3 . This can form three S i - O - S i linkages, thus produces cross linked polymers.
