In which of the following molecules would you expect the nitrogen-to-nitrogen bond length to be the shortest?

What is the bond order of the $O_2$ molecule?

Using $MO$ theory,predict which of the following species has the shortest bond length?

Stability of the species $Li_2$,$Li_2^-$ and $Li_2^+$ increases in the order of $:-$

The sum of the bond orders of $O_2^{2+}, O_2^{2-}, O_2^{+}, O_2^{-}, O_2$ and the sum of the unpaired electrons present in them respectively are

For $F_2$ and $OF$ molecules,consider the following statements:
$(a)$ Bond order for both is one
$(b)$ $OF$ is paramagnetic but $F_2$ is diamagnetic
$(c)$ $F_2$ is more likely to dissociate into atoms than $OF$
$(d)$ Both have greater number of electrons in $BMO$ than that in $ABMO$
Which of the following statements are true $(T)$ or false $(F)$ respectively?
