Identify the incorrect statement

A
In $(Si_3O_9)^{6-}$, tetrahedral $SiO_4$ units share two oxygen atoms
✓
Trialkylchlorosilane on hydrolysis gives $R_3SiOH$.
C
$SiCl_4$ undergoes hydrolysis to give $H_4SiO_4$
D
$(Si_3O_9)^{6-}$ has cyclic structure.

✓

Answer

Correct option: B.

Trialkylchlorosilane on hydrolysis gives $R_3SiOH$.

b
The hydrolysis of Trialkylchlorosilane $R_3SiCl$ yields dimer :
