Answer : The Lewis-dot structure of [tex]SOCl_2[/tex] is shown below.
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'.
The given molecule is, [tex]SOCl_2[/tex]
As we know that sulfur has '6' valence electrons, chlorine has '7' valence electrons and oxygen has '6' valence electrons.
Therefore, the total number of valence electrons in [tex]SOCl_2[/tex] = 6 + 6 + 2(7) = 26
According to Lewis-dot structure, there are 8 number of bonding electrons and 18 number of non-bonding electrons.
Now we have to determine the formal charge for each atom.
Formula for formal charge :
[tex]\text{Formal charge}=\text{Valence electrons}-\text{Non-bonding electrons}-\frac{\text{Bonding electrons}}{2}[/tex]
[tex]\text{Formal charge on O}=6-6-\frac{2}{2}=-1[/tex]
[tex]\text{Formal charge on }Cl_1=7-6-\frac{2}{2}=0[/tex]
[tex]\text{Formal charge on }Cl_2=7-6-\frac{2}{2}=0[/tex]
[tex]\text{Formal charge on S}=6-3-\frac{6}{2}=+1[/tex]
Hence, the Lewis-dot structure of [tex]SOCl_2[/tex] is shown below.
