Discussion Overview

The discussion revolves around the bonding characteristics of nitrogen, particularly focusing on how nitrogen forms bonds with its electrons in the 2p orbital and the implications for nitric oxide. Participants explore the mechanisms of bond formation, including the roles of different electron orbitals and the concept of bond order.

Discussion Character

  • Exploratory
  • Technical explanation
  • Conceptual clarification
  • Debate/contested

Main Points Raised

  • Some participants propose that nitrogen makes two bonds by transferring one electron from the 2s orbital to a 2p orbital, allowing for bonding with two of the 2p orbitals.
  • Others argue that nitrogen actually forms three bonds, with two p-electrons forming a sigma bond and two additional p-electrons forming two pi bonds, while the s-electrons do not contribute to bonding.
  • A later reply questions the bonding situation in nitric oxide, suggesting that it has an additional electron leading to a 3-electron pi bond, resulting in a bond order of 2.5.
  • Another participant clarifies that the extra electron in nitric oxide does not belong solely to nitrogen or oxygen but populates an anti-bonding pi orbital.
  • There is a request for further elaboration on how the extra electron affects bonding, indicating a need for understanding molecular orbital theory (MOT).

Areas of Agreement / Disagreement

Participants express differing views on the number of bonds nitrogen forms and the role of the extra electron in nitric oxide. The discussion remains unresolved regarding the exact mechanisms and implications of these bonding characteristics.

Contextual Notes

Participants reference concepts such as bond order and molecular orbital theory, indicating that a deeper understanding of these topics may be necessary to fully grasp the discussion.

Who May Find This Useful

This discussion may be useful for students or individuals interested in molecular chemistry, particularly those studying the bonding behavior of nitrogen and its compounds.

Guys, I'm just thinking about how Nitrogen makes two bonds if it has 3 electrons in 2p orbital. I made a judgement that one electron from 2s orbital will transfer to one of 2p orbitals then there are two 2p orbitals which can make a bond? Is this correct or there is other mechanism?

Nitrogen actually makes 3 bonds. 2 p-electrons form a sigma-bond and 2 x 2 p-electrons form 2 pi-bonds. The s-electrons are not binding.

Yeah but what's happening in the case of Nitric oxide?
 
In nitric oxide, you have one additional electron, so you will get a 3-electron pi bond which is about half as strong as a 2 electron pi bond. So you will get an overall bond order of 2.5.

Can you just elaborate. Extra electron means tha nitrogen gains a electron then it makes a bond?
 
No, I meant that in nitric oxide you have one more valence electron as compared to dinitrogen.

The extra electron populates an anti-binding pi orbital. It belongs to the molecule and not to nitrogen or oxygen only.

Ohk to understand this concept should I first understand MOT
