What would be the product of following reaction SiCl 4 ⟶   Excess   of   H 2 O ?…

We know that when silicon tetrachloride react with excess of water then it undergoes in full hydrolysis.

The condition of hydrolysis is there should be presence of vacant orbital and there should be lesser stearic hindrance. Hence,

${\mathrm{SiCl}}_4 \stackrel{{\mathrm{H}}_2\mathrm{O} \left(\mathrm{excess}\right)}{\to } \mathrm{Si}{\left(\mathrm{OH}\right)}_4$
