Why CCl4 does not act as lwise acid while SnCl4 do so?

We know C atom is an element of 2nd period in  the periodic table and obviously having no D orbital. 

C(6)➡1s2 2s2 2px1 2py1

The first codition of a compound to acts as a lwise acid is capable of receiving a pair of electron. I.e. Election pair receiver are lwise acid. 

As Carbon atom has no D orbital in CCl4 carbon could not capable of   receiving and unable to accommodate the received pair of electron .

On the other hand Si is an element of 3rd period in the periodic table  and having D orbital,  

Si(14)➡1s2 2s2  2p6  3s2 3p2 3d0 

the electrons of ultimate shell enters into the P orbital but having empty  D orbital  because of having D orbital it is able to receive  a paire of electron and can accommodate these in SiCl4 molecule. 

Which fullfill the condition of becoming a lwise acid. 

Thats why CCl4 does not acts as a lwise acid  but SiCl4 can do so.
