Question

Draw electron dot representation of $ \text{CC}{{\text{l}}_{\text{4}}} $ .

Answer 1

Hint: A Lewis electron dot diagram is a representation of the valence shell electrons of an atom that uses dots around the symbol of the central element as a representation of the electrons. The bonds are represented as pairs of electrons shared.

Complete Stepwise solution
In carbon tetrachloride or $ \text{CC}{{\text{l}}_{\text{4}}} $ , the central element is carbon, whose valence shell has four electrons and the number of electrons in the valence shell of the chlorine is seven. So the carbon atom needs four more electrons in the valence shell while chlorine needs only one more electron, hence they share the electrons to form four covalent bonds. Each carbon atom forms one covalent bond with each chlorine atom. The electronic representation of the compound is as follows:

In the above figure, the carbon atom is seen to share four of its valence electrons with one valence electron of the chlorine atom and thus form a strong covalent bond. This also leads to fulfilment of their octet.

Note
The Lewis electron dot configuration is a way to represent the molecular bond formation of a compound in a pictorial manner. But this technique is not used as much as it was used before nowadays. This is because these structures are two-dimensional figures that cannot predict the stereochemistry of a compound or the arrangement of the different atoms in the molecule in space around the atom.
Nonetheless, these structures provide preliminary knowledge about the bonding pattern and hence are useful to predict the bonding nature of a covalent or ionic molecule.
