Lewis Structure on (CH3)2NO?

I've been taking an chemistry class online (for fun only) and one of the questions in the homework threw me a bit. Here's the wording:


"Draw the Lewis structure for a nitrogen atom attached to. two methyl groups ($\ce{CH3}$) and one oxygen atom."


OK, so I know that $\ce{NO}$ is a free radical due to the odd combined valence, i.e., the octet rule isn't satisfied. Will that carry over when the $\ce{NO}$ bonds with the two methyl groups?


Here's the sketch of what I did:

Lastly, what's the name of this compound? This is not part of the HW question; I'm just curious.




* Name of the compund: **Dimethyl nitroxide**
* Lewis structure:

* The properly way to determine the Lewis structure, based on this example, is:


	1. Total valence electrons: $4\cdot2 + 5 + 6 + 1\cdot6 = 25$
	2. Total electrons needed for octets/doublets: $8\cdot4+2\cdot6 = 44$
	3. Total shared/bonding electrons: $44 - 25 = 19$ (In other words, there is only nine single bonds and one electron left.)
	4. Total electrons in lone pairs: $\text{Step 1} - \text{Step 3} = 25 - 19 = 6$ (In other words, the are only 3 pairs of lone electrons.)

* Further information of related Lewis structures and how this knowledge is applied on real top science, I recommend seeing this [reference:](http://www.beilstein-journals.org/bjoc/single/articleFullText.htm?publicId=1860-5397-9-181) Moreira, G.; Charles, L.; Major, M.; Vacandio, F.; Guillaneuf, Y.; Lefay, C. and Gigmes, D. *Beilstein J.
