Lewis dot structures – Electron dot structure of NO

Lewis dot structures of NO│Lewis dot of Nitrogen Monoxide (NO)

A simple method for writing Lewis Electron Dot Structures (Dot Electron Structures) was 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).

Let us consider the case of NO. NO is a free radical and is an important intermediate in the chemical industry. Nitric oxide is a by-product of combustion of substances as in automobile engines, fossil fuel power plants, and is produced naturally during the electrical discharges of lightning in thunderstorms. In mammals including humans, NO is an important cellular signaling molecule involved in many physiological and pathological processes. The vasodilating antihypertensive drug minoxidil contains an NO moiety and may act as an NO agonist. Likewise, Sildenafil citrate, popularly known by the trade name Viagra, stimulates erections primarily by enhancing signaling through the nitric oxide pathway in the penis.

Let us draw the Lewis dot structures of Nitrogen Monoxide (NO).

Draw Lewis structures of NO step by step:

Draw Lewis structures
The Lewis structures of Nitrogen Monoxide NO are drawn.
1.N
2.Total valence electron is 5+6= 11
Connect the atoms of NO with single bonds
3.Connect the atoms with single bonds.
4.P=6n+2 -V =6×2 +2 -11 = 14-11 = 3 ; 3 electron which must be shared through pi bonding and unshared i.e; Therefore, there is 1 double bond and an electron..
5.Distribution of other electron
6. Complete the octet shells
7. Calculare the formal charege….

The lone electron is placed on the N atom which is more electropositive than O and can accommodate better a positive charge
