Question: On controlled hydrolysis and condensation, $ R_3SiCl $ yields
[Orissa JEE 2005]
Options:
A) $ R_3Si-O-SiR_3 $
B) ( $ R_3Si-O-SiR_3 $ )n
C) $ R_3SiOH $
D) $ \overset{RR}{\mathop{\overset{||}{\mathop{\overset{-Si-O-Si-}{\mathop{\underset{||}{\mathop{\underset{-Si-O-Si-}{\mathop{\underset{OO}{\mathop{||}}}}}}}}}}}} $
Show Answer
Answer:
Correct Answer: A
Solution:
$ R_3SiCl $ on hydrolysis forms only a dimer. $ R_3SiOH+HOSiR_3\to R_3Si-O-SiR_3 $ .
