Question

Use Lewis theory to draw the structure of the compound containing 1 carbon and 4 chlorine atoms. What would you find surrounding the central atom of this ion?

A. 1 double bond.
B. no double bonds.
C. 2 double bonds.
D. 1 triple bond.
E. none of the above

Answer 1

Answer : The correct option is, (B) no double bonds.

Explanation :

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

In the Lewis-dot structure the valance electrons are shown by 'dot'.

As we are given that the structure of the compound containing 1 carbon and 4 chlorine atoms.

Thus, the molecule is,
`CCl_4`

As we know that carbon has '4' valence electrons and chlorine has '7' valence electrons.

Therefore, the total number of valence electrons in
`CCl_4` = 4 + 4(7) = 32

According to Lewis-dot structure, there are 8 number of bonding electrons and 24 number of non-bonding electrons.

From the Lewis-dot structure we conclude that there are 4 single bonds are surrounding the central atom of this ion there is no double or triple bonds are present.

Hence, the correct option is, (B) no double bonds.
