Which of the following species contains only $\pi$-bonds but exhibits paramagnetic nature?

If the bond order in $C_2$ is '$x$',then the bond order in $B_2$ and $O_2$,respectively,are

Which of the following molecules has a bond order of $2$?

$AX$ is a covalent diatomic molecule where $A$ and $X$ are second row elements of the periodic table. Based on Molecular Orbital Theory,the bond order of $AX$ is $2.5$. The total number of electrons in $AX$ is ........... (Round off to the nearest integer).

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?

Identify the correct increasing order of energies of molecular orbitals for the $F_2$ molecule.
