The Total solution for NCERT class 6-12
Use molecular orbital theory to explain whythe Be2 molecule does not exist.
The electronic configuration of Beryllium is
The molecular orbital electronicconfiguration for Be2 molecule can be written as:
Hence, the bond order for Be2 is
Where,
Nb = Number ofelectrons in bonding orbitals
Na = Number ofelectrons in anti-bonding orbitals
Bond order of Be2 = 0
