Expert Answer

Use the bond's Lewis dot structure as a starting point. You can reference bonding diagrams, too.

Question

What is the formula of bond order?

Suraj Mehta

Community Answer

For finding bond order the general formula is (# of bonding electrons in mo) - (# of antibonding electrons in mo) / 2.

Question

Why is super oxide more paramagnetic than peroxide?

Community Answer

Because the natural formula of the paramagnetic table states that super oxide can expand more at a time than peroxide.

Question

What is the bond order of clO4-?

Aquaeika

Community Answer

Bond order will be apparent if you draw a valence structure of ClO4-. Hint: Cl has 7 valence electrons, O has 6 valence electrons (but some will be non-bonding i.e. lone pairs). O follows octet rules but Cl can be hypervalent.

Question

What is the bond order of CO?

Babu Guguloth

Community Answer

Bond order is 3, because if electrons are removed from bonding molecular orbitals or added to anti bonding molecular orbitals then the bond order decreased from 4 to 3.

Question

What is the bond order of N2?

Community Answer

If you draw the Lewis structure of N2 you will get a triple bond, which indicates bond order. So N2 has a bond order numerically equal to 3.

Question

How do I find the bond order of an element?

Community Answer

The formula is 3-(n/2) where n is the difference of total electrons from 14. For example, N2 having total electrons of 7+7=14, subtract 14 and you will get n. Substitute in the formula and you get the bond order as 3.
