How do I draw a Lewis structure of a molecule - Lewis structure of nitryl chloride NO2Cl

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 nitryl chloride NO2Cl.


Step 1: The central atom is the N atom. Connect the atoms with single bonds. 

Fig. 1 : Connect the atoms of NO2Cl with single bonds.

Step 2: Calculate the # of electrons in π bonds (pi bonds, multiple bonds)  using  formula (1):

Where n in this case is 4. Where V = 5 + 2*6 + 7 = 24 , V is the number of valence electrons of the compound.
Therefore, P = 6n + 2 – V = 6 * 4 + 2 – 24  = 2     So, there is 1 double bond


Step 3 & 4: The  Lewis dot resonance structures of  NO2Cl  are as follows:
