# What is the molecular structure of "nitrous oxide", N_2O?

Feb 9, 2017

$\text{Nitrous oxide}$ is linear.

#### Explanation:

And how do we know? Well, by experiment, and measurement, but VESPER gives a good approximation. We have $2 \times 5 + 6 = 16$ $\text{valence electrons}$ to distribute over 3 centres.

A structure of $N \equiv {N}^{+} - {O}^{-}$ is reasonable, even tho it invokes formal charge separation. Its resonance structure of ""^(-)N=N^(+)=O is formally equivalent. Disregarding the multiple bonds, there are 2 regions of electron density around the central nitrogen, and VESPER would predict that $\angle O - N - O = {180}^{\circ}$, and experiment confirms this.

It's a linear...

#### Explanation:

It has a big explanation cause it needs the electrically neutrality. But it's structure is like this. It's one of the 8 Lewis structures it can have:
${.}^{-} N = {N}^{+} = O$
