As per MOT $C_{2}$ molecule have :-

Answer:

Solution:

According to MOT, bond strength depends on bond order; a higher bond order means a stronger and shorter bond.

B₂ has 6 valence electrons and a bond order of 1.

C₂ has 8 valence electrons and a bond order of 2 due to more electrons in bonding orbitals.

Therefore, C₂ has a higher bond order than B₂, making its bond stronger and shorter.

$C_{2} > B_{2} (s t re n g t h) an d C_{2} < B_{2} (b o n d l e n g t h)$

Answer: (A) Stronger & shorter bond than B₂
