A) In\[{{(\operatorname{S}{{\operatorname{i}}_{3}}{{\operatorname{O}}_{9}})}^{6-}}\], tetrahedral \[Si{{O}_{4}}\] units share two oxygen atoms.
B) Trialkylchlorosilaneon hydrolysis gives \[{{R}_{3}}SiOH\]
C) \[SiC{{l}_{4}}\]undergoes hydrolysis to give \[{{H}_{4}}Si{{O}_{4}}\]
D) \[{{(\operatorname{S}{{\operatorname{i}}_{3}}{{\operatorname{O}}_{9}})}^{6-}}\]has cyclic structure
Correct Answer: B
Solution :
The hydrolysis of Trialkylchlorosilane \[{{R}_{3}}SiCl\]yields dimer: \[R-\underset{\begin{smallmatrix} | \\ R \end{smallmatrix}}{\overset{\begin{smallmatrix} R \\ | \end{smallmatrix}}{\mathop{Si}}}\,-O-\underset{\begin{smallmatrix} | \\ R \end{smallmatrix}}{\overset{\begin{smallmatrix} R \\ | \end{smallmatrix}}{\mathop{Si}}}\,-R\]
