Choose the statement that is not correct:

1. In (Si3O9)6−, each SiO4 tetrahedron shares two oxygen atoms.
2. Hydrolysis of a trialkylchlorosilane produces R3SiOH.
3. SiCl4 on hydrolysis yields H4SiO4.
4. The ion (Si3O9)6− has a ring-shaped structure.

Correct answer: Hydrolysis of a trialkylchlorosilane produces R3SiOH.

Solution

The statement about the hydrolysis of a trialkylchlorosilane producing R3SiOH is incorrect because the hydrolysis of trialkylchlorosilanes typically results in the formation of silanol (R3SiOH) and hydrochloric acid, but the context implies a misunderstanding of the product formation.
