Match the bond order for the following molecules.

The correct answer is

Options

A. `{:(A,B,C,D),(II,III,I,V):}`
B. `{:(A,B,C,D),(III,I,IV,V):}`
C. `{:(A,B,C,D),(IV,I,V,III):}`
D. `{:(A,B,C,D),(III,II,V,I):}`

Answer

B

Explanation

Bond order the nu,ber of chemical bonds between a pair of atom. So,
(B.O)
`Li_(2)=Li-Li` (1)
`N_(2)=N -= N` (3)
`Be_(2)= Be. Be` (No bond) (0)
`O_(2) = O = O` (2)
Note Zero bond order means the molecule is too unstable and so it will not exit.
Electrons will fill according to the energy levels of the orbitals.
