Question

What is the correct order of hydrolysis and why?
(a) NaCl < MgCl2 < AlCl3 < SiCl4 < PCl5
(b) CCl4 < SiCl4 < GeCl4 < SnCl4 < PbCl4
(c) SF6 < SeF6 < TeF6
(d) Both (a) and (c)

Answer 1

The hydrolysis increases with the increase in oxidation number.
Oxidation number increases in (a), (b) and (c) rows.
So that the correct order of hydrolysis is: a, b, c.
