$SF_{6}$

Vedclass · Answer

(D) The molecule,which is not hydrolysed by water at $25^{\circ} C$ is $SF_{6}$. This is because it is kinetically stabilised,attack at $S$ is impossible due to steric hindrance and also because of the coordination saturation of $S$ atom by $6$ $F$ atoms. The hydrolysis reactions of other molecules are as follows: $AlCl_{3} + 3H_{2}O \longrightarrow Al(OH)_{3} + 3HCl$ $SiCl_{4} + 2H_{2}O \longrightarrow 4HCl + SiO_{2}$ $BF_{3} + 3H_{2}O \longrightarrow H_{3}BO_{3} + 3HF$
