Understand Lewis Dot Structures: Cl F & Triple Bonds

[Gokul43201]

No, it's better because O gets an octet. Yes, sometimes there are multiple answers, and the actual structure is a resonance of the different possibilities. This is true if the different answers are equally good. However, here, there is one solution that is better than others, so it must be chosen.

Too late here too ...g'night !

Okay,Gokul,you're right:In this formula $$NOF_{2}$$ with the Lewis structure:

$$\cdot$$​

$$|\overline{\underline{F}}-N=\overline{O}|$$​

|​

$$|\underline{F}|$$​

The total number of electrons is as it should be:25 and the oxydation number of nytrogen is +4,which means that the "NO" combination has the ON "+2".

I believe they are called "mesomeric" structures and have been discovered by Linus Pauling in the early 1930's.

Dexter, this lends naturally to another solution :

$$(2+) ~~ \cdot N = \overline{O} |$$

And i believe that oxygen looks pretty good:no triple bond,no "forced" octet...Poor nytrogen,stripped of two electrons...
