Question

SiCl₄ is easily hydrolysed but CCl₄ is not. This is because 

(a) bonding in SiCl₄ is ionic 

(b) silicon is non-metallic 

(c) silicon can extend its coordination number beyond four but carbon cannot 

(d) silicon can form hydrogen bonds but carbon cannot.

Answer 1

Correct option (c)

Explanation:

SiCl₄ is easily hydrolysed because Si can extend its coordination number beyond four due to the presence of vacant d-orbitals but carbon cannot do so, hence it is not hydrolysed.
