Simple Procedure for writing Lewis Structures – Lewis Structures for Nitrogen Oxychloride NOCl

Lewis structures of NOCl

Lewis Structures for Nitrogen Oxychloride NOCl

A simple procedure for writing Lewis 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.

Nitrogen Oxychloride is a yellow gas. It is used in synthesis of pharmaceutical products (chlorinated agent).

 

Step 1:  The central atom will be the N atom since it is the less electronegative. Connect the atoms with single bonds:

NOCl atoms connected only with single bonds

 

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  NOCl consists of three atoms.

Where V = (5 + 6 +7 ) = 18  

Therefore, P = 6n + 2 – V = 6 * 3 + 2 – 18 = 2     So,   there are 2π electrons in NOCl .

 

Step 3 & 4: Therefore, the Lewis electron dot structure of NOCl are as follows:

Lewis structures for NOCl. Resonace structure 1 is the most plausible since there is no charge separation
