Arrange in increasing order of extent of hydrolysis [ CCI4, MgCI2, AICI3, PCl5, SiCI4].

We know that CCI₄ does not undergo hydrolysis since "C" does not have d orbital. The central atom of all other element contains empty d-orbitals and hence undergoes hydrolysis. As the oxidation state of the central atom increases from +2 (MgCI₂) to +3 (AICI₃) to +4 (SiCI₄) to +5 (PCl₅), the extent of hydrolysis increases accordingly. Thus, the overall increasing order of extent of hydrolysis follows the order: 

 ["CCI₄ < MgCI₂ < AICl₃ < SiCl₄ < PCl₅"]
