Silicon (IV) chloride on hydrolysis gives an acid \(X\). The number of \(-OH\) groups present in \(X\) is

Question

Given below are two statements:
Statement I: The electronegativity of group 14 elements from Si to Pb gradually decreases.
Statement II: Group 14 contains non-metallic, metallic, as well as metalloid elements.
In the light of the above statements, choose the most appropriate from the options given below:

Answer 1

Step 1: Write and count products of hydrolysis.
SiCl₄ + 4H₂O → Si(OH)₄ + 4HCl. Orthosilicic acid Si(OH)₄ has exactly 4 hydroxyl groups attached to the central silicon.

Step 2: Final Answer:
4 (option 4).
