Lewis Dot Structures of chlorine dioxide cation clo2+

# of chlorine dioxide cation (ClO2)+

A simple procedure for writing Lewis electron dot structures is given in a previous article 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).

Another example  for writing Lewis structures following the above procedure is given below.

How can we draw the Lewis structures of (ClO2)+?

Step 1: Connect the atoms with single bonds. Chlorine is the central atom. Step 2: Calculate the # of electrons in π bonds (multiple bonds) using  formula (1) in the article entitled “Lewis Structures and the Octet Rule”.

Where n in this case is 3 since (ClO2)+ consists of three atoms.

Where V = (7 + 6 + 6 ) – 1 = 18

Therefore, P = 6n + 2 – V = 6 * 3 + 2 – 18 = 2

So, there are 2 π electrons (pi electrons) in (ClO2)+ and the structure in Step 1 has 1 double bond.

So the structure of Step 1 is the Lewis structure.

Electrons are placed around each atom so that the octet rule is obeyed. Since Cl is a third row element can accommodate more than 8 electrons.

Step 3 & 4: The Lewis resonance structures of  ClO2+   are as follows: The most stable resonance structure is #4 since it has the smallest charge separation and the positive charge is on the Cl atom which is less electronegative than O.
