Assertion :Tetrachloride of group 14th elements except CCl4 are easily hydrolysed by water. Reason: The central atoms of these chlorides can accomodate the lone pair of electrons from oxygen atom of water molecule in d-orbitals.

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for AssertionSiCl4+4H2O→H4SiO4 or Si(OH)4 (ortho silicic acid)+4HCl

Assertion :Tetrachloride of group $14^{t h}$ elements except $C C l_{4}$ are easily hydrolysed by water. Reason: The central atoms of these chlorides can accomodate the lone pair of electrons from oxygen atom of water molecule in d-orbitals.

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
$S i C l_{4} + 4 H_{2} O \to H_{4} S i O_{4}$ or $S i (O H)_{4}$ (ortho silicic acid)+4HCl
