explain molecular orbital enargy level diagrams of CO and N2.
Answers
Answer:
The bond order shows the number of chemical bonds present between a pair of atoms. The Bond Order Formula can be defined as half of the difference between the number of electrons in bonding orbitals and antibonding orbitals.
Bond order formula is given as below
Bondorder=1/2[a–b]
where
a = Number of electrons in bonding molecular orbitals.
b = Number of electrons in antibonding molecular orbitals.
(i) Structure of N2
Electronic configuration of N2 (14 electrons) = (σ1s)2(σ*1s)2(σ2s)2(σ*2s)2(π)4(2pz)2
a = 10
b= 4
Bond order = 1/2 (10 – 4)
Bond order = 3
Explanation:
As it can be seen from the MOT of O
2
, The electrons in the highest occupied molecular orbital are unpaired therefore it is paramagnetic in nature. Also, the bond order can be calculated as [N
b
−N
a
]/2=[10−6]/2=2. Therefore there is a double bond present as O=O.
