What is the Lewis dot structure of NO2 cationic ligand?

Answer 1

.

O_N_O

--- Uh. I don't think so. NO2 doesn't come out so pretty.

There are exceptions to our good friend, the octet rule. Things get sticky here.

First of all, you have to calculate the valence electrons of the molecule. (You see this by the group they're in.)

So,

N = 5

O = 6 (but there's 2!) so that's 12.

12 + 5 = 17.

Uh oh. Houston, we have a problem.

Electrons like to "pair up", so having an odd number of e- messes things up (in other words, the bond that carries that one lonely e- is really "freaking out" aka it really isn't that stable.)

There is absolutely no way you can satisfy the octet rule. (Trust me, if you wanna try it anyway, be my guest.)

So, the closest you can get is:

O - N = O

(don't forget to add the dots/electrons! On mine, I showed the extra electron being on one of the oxygen's.) I know, I know. It's weird.

Hope I helped!

Answer 2

O=N-O

The Oxygen on the left double bonds to the Nitrogen. The Oxygen on the right forms a single bond with the Nitrogen.

Left Oxygen: 2 pairs of electrons are in their own sublevels, the other two help form the double bond with Nitrogen.

Nitrogen: 2 electrons are used in the double bond on the left, while 2 others go to the single bond to the left. Its last electon will fill in the last sublevel along with the extra electron from the 1- charge.

Right Oxygen: It free-loads on Nitrogen, bonding to Nitrogen's 2 electrons in the single bond. The Oxygen's 6 electrons fill in the last 3 sublevels, with 2 in each.

Answer 3

this is one of those molecules that doesnt obey the octet rule. a double bond between N and O (N=O), with 3 unbonded electrons on N, and 4 unbonded electrons on O. the NO2 is similar, although it would be O-N=O, with 4 unbonded electrons on the double bonded Oxygen, 6 unbonded on the single bond Oxygen and 1 electron on N.

Answer 4

It will actually resonate between structures, but generally the Nitrogen between the two Oxygen molecules will have a lone pair of electrons, with double bond to one oxygen and a single bond to the other oxygen which has 3 lone pairs and as such is negatively charged. If the Nitrogen functions as the nucleophilic atom it will be positively charged when a fourth bond is formed.

Answer 5

N and O are formed by two covalent bonds and one coordinate bond from oxygen to nitrogen.
