SiF 4 gets hydrolysed giving

Question

SiF 4 gets hydrolysed giving (A) SiO 2 (B) Si(OH)2 F 2 (C) H 2 SiF 6 (D) Si(OH)4

SiF 4+4 H 2 O arrow Si ( OH )4+4 HCl The trend towards hydrolysis decreases down the group. Silicon have vacant orbital to which water molecules can co-ordinate and hence their halides are hydrolysed by water.

Q. $S i F_{4}$ gets hydrolysed giving

$S i O_{2}$

$S i (O H)_{2} F_{2}$

$H_{2} S i F_{6}$

$S i (O H)_{4}$

$S i F_{4} + 4 H_{2} O \to S i (O H)_{4} + 4 H Cl$
