Answer to Question #280031 in General Chemistry for Venus

Question

Write the correct Lewis structure of product and show the step-by-step solution on how you came up with the structure.

SOCl2- primarily used as a chlorinating reagent.

Answer 1

Lewis structure of SOCl$_2$

Number of valence electrons

$=6+6+7(2)$

$=26$

Adding dots

Formal charge$=$ $\begin{matrix} Valence \>electrons- Non\>Bonding \>val\>electrons&-\frac{Bonding\>electrons}{2} \end{matrix}$

$Cl=7-6-\frac{2}{2}=0\\S=6-2-\frac{6}{2}=+1\\O=6-6-\frac{2}{2}=-1$

Improved structure

Formal charges;

$Cl=7-6-\frac{2}{2}=0\\S=6-2-\frac{8}{2}=0\\O=6-4-\frac{4}{2}=0$

This is the best structure
