Carbon tetrachloride is a tetrahedral molecule formed when carbon combines with 4 chlorine atoms.

The carbon atom has 4 electrons in its outermost electron shell. Each chlorine atom has 7 electrons in its outermost electron shell. When one electron is shared by carbon with each of the four chlorine atoms all the 5 atoms achieve a stable outermost electron shell configuration of a noble gas.

As carbon which is the central atom in CCl4 has to share all four of it electrons with each of the 4 chlorine atoms there are no unshared pairs of electrons.
