Q52.Identify the incorrect statement: (1) In (Si3O9)6− , tetrahedral SiO4 units share two (2) Trialkylchlorosilane on hydrolysis gives R3SiOH oxygen atoms. . (3) SiCl4 undergoes hydrolysis to give H4SiO4 . (4) (Si3O9)6− has cyclic structure.
What This Question Tests
This question tests knowledge about various silicon compounds and their properties, specifically focusing on silicates and hydrolysis products of chlorosilanes. Statement (3) is often considered 'incorrect' because H4SiO4 is an unstable intermediate that rapidly polymerizes.
