Which is more stable O2 or N2 and why? |
| Answer» Molecular orbitals of nitrogen and oxygen is as below:\xa0Nitrogen molecule has 14 electrons. So the electron distributions in molecular orbital are as below\xa0N2\xa0= σ1s2\xa0σ*1s2 σ2s2\xa0σ*2s2 σ2px2 π(2py22pz2) \xa0Bond order = (No. of electrons in bonding orbitals - No. of electrons in bonding orbitals)/2 =(10-4)/2 = 3\xa0Oxygen molecule has 16 electrons. So the electron distributions in molecular orbital are as below\xa0O2\xa0= σ1s2\xa0σ*1s2 σ2s2\xa0σ*2s2 σ2px2 π(2py22pz2) π*(2py1\xa02pz1)Bond order= (10-6)/2 = 2\xa0As bond order of nitrogen is more than that of oxygen, nitrogen is more stable than oxygen. | |
