# Simple Method for writing Lewis Structures for Carbon Disulfide CS_{2}

A simple procedure for writing Lewis Dot Structures** **was given in a previous post entitled “**Lewis Structures and the Octet Rule**”.
Several worked examples relevant to this procedure were given in previous posts please see the Sitemap - Table of Contents (Lewis Electron Dot Structures).

Let us consider the case of the **Lewis dot structures of carbon disulfide CS _{2}.**

__Step 1__: Connect the atoms with single bonds. Carbon is the central atom since it is less electronegative.

__Step 2__:
Calculate the # of
electrons in π bonds (multiple bonds) using formula (1):

Where n in this
case is 3 since CS_{2} consists
of three atoms.

Where V = (4 + 6 + 6 ) = 16

Therefore, P = 6n
+ 2 – V = 6 * 3 + 2 – 16 = 4 So there are 4π electrons in CS_{2} and that means 2 double bonds or a triple bond must be added to the structure in
Step 1.

__Step 3 & 4__: The Lewis structure for CS_{2} is as
follows:
