Question

Make a sketch showing the location and geometry of the
p orbitals in the nitrite ion, NO2-. Describe the bonding in
this ion using a localized valence bond model for s bonding
and a delocalized MO model for p bonding.

Accepted Answer

Hey everyone, we're asked to draw a diagram that illustrates the position and geometry of the p orbital's in ozone. Using a localized valence bond model for sigma bonds and a d localized molecular orbital model for pi bonds, explained the bonding in the compound 1st. Let's go ahead and draw out our structure. So we have our ozone and oxygen is in our group six. A and since we have three of oxygen, we're going to multiply six times three to get 18 valence electrons drawing out our lewis structure. We have three oxygen's bonded to one another. one will be double bonded while one will be single bonded, adding in our loan pairs. We get the following structure And our oxygen in the middle will have a plus one formal charge, while our oxygen to the right will have a -1 formal charge. And here we can see resonance as possible. So moving over our double bond to the right and our single bond to the left, We get that -1 formal charge on our left oxygen and we get that plus one formal charge on our middle oxygen, drawing out our resonance hybrid, we get the following structure. So we show that our oxygen's are single bonded and we will also show that we have two lone pairs on our outer oxygen's. And we will have this dash line to signify our resonance. So our outer oxygen's will have a minus one half charge, while our middle oxygen will still have that plus one charge. Now let's go ahead and draw out our sigma bond. So our sigma bond is and on overlap of orbital's drawing this out, it will be our oxygen's single bonded to one another, and we will have three lone pairs onto our outer oxygen's and one lone pair in our middle oxygen. Now let's go ahead and draw out our pi bond. Our pi bond is going to be our orbital's overlapping laterally or in a side by side fashion, drawing this out, we have our three oxygen's bonded to one another. Now we're going to go ahead and draw in our orbital's and we're going to show that they overlap laterally through these yellow lines. So this is going to be our final answer for this question. Now, I hope that made sense. And let us know if you have any questions.
