What is the bond order of NO-, NO, and NO+?

In summary, the bond order of NO is 2, with one bond and one anti-bonding orbital, while the bond order of NO+ is 3, with a triple bond and no anti-bonding orbitals. The Lewis structure of NO is a double bond between nitrogen and oxygen, with nitrogen having 5 electrons and oxygen having a full octet. The reason for this is that oxygen is more electronegative and therefore attracts more electrons. Using molecular orbital theory, the bond order can be calculated by subtracting the number of electrons in anti-bonding orbitals from the number of electrons in bonding orbitals and dividing by two.

The Attempt at a Solution



I determined the Bond order of NO+ to be 3 due to their triple bond and the
Bond order of NO- to be 1 due to their single bond

Lewis Structures probably
I don't Know how to write the Lewis Structure of NO, as the total electrons is 11, and by looking at a diagram on google images :D, i saw that oxygen had a full octet and nitrogen had 5 electrons, and they were connected by a double bond. But this diagram seems so odd? And any reason why Oxygen has a full octet but not Nitrogen? Any clarification??

Use molecular orbital theory to calculate bonding & non bonding molecular orbital..bond order=(no of electrons in bonding molecular orbital)-(no of electrons in non bonding molecular orbital)/2
 

FAQ: What is the bond order of NO-, NO, and NO+?

What is bond order?

Bond order is a measure of the number of chemical bonds between a pair of atoms. It is typically represented by a number, with higher numbers indicating stronger bonding.

How is bond order calculated?

Bond order is calculated by subtracting the number of anti-bonding electrons from the number of bonding electrons and dividing by two. This can be determined by drawing the Lewis structure and counting the number of bonding and anti-bonding electron pairs.

What is the relationship between bond order and bond length?

The higher the bond order, the shorter the bond length. This is because higher bond order indicates stronger bonding, so the atoms are held closer together.

What is the significance of bond order in chemical reactions?

The bond order between atoms can determine the stability and reactivity of a molecule. Higher bond order can make a molecule more stable, while lower bond order can make it more reactive. This can affect the rate and direction of chemical reactions.

How does bond order impact the physical properties of a molecule?

The strength of a chemical bond, determined by bond order, can influence the physical properties of a molecule such as melting and boiling points, density, and solubility. Higher bond order can result in higher melting and boiling points, while lower bond order can result in lower melting and boiling points.
