Which is the correct lewis structure for carbon tetrabromide (cbr4), in which a central carbon atom is bound to four atoms of the group 7a element bromine?

a.)
b.)
c.)
d.)

Answer : The correct option is, (B)

Explanation :

Lewis-dot structure : It is defined as the it shows the bonding between the atoms of a molecule and it also shows the unpaired electrons present in the molecule.

The given molecule is, carbon tetrabromide

As we know that the carbon has '4' valence electrons, bromine has '7' valence electron.

Therefore, the total number of valence electrons in = 4 + 4(7) = 32

According to Lewis-dot structure, there are 8 number of bonding electrons present between the carbon-bromine and 24 number of non-bonding electrons present on the bromine.

Hence, the correct option is, (B)

the answer is d.) potassium
