The species,which has the bond order same as that of $F_2$ molecule is

Number of molecules having bond order $2$ from the following molecules is: $C_2, O_2, Be_2, Li_2, Ne_2, N_2, He_2$

Answer the following questions:
$(i)$ Give the molecular orbitals and their types formed by $LCAO$ from $2s, 2p_{x}, 2p_{y}$ and $2p_{z}$ atomic orbitals.
$(ii)$ Provide the energy order of molecular orbitals for $Li_{2}, Be_{2}, C_{2}, N_{2}, O_{2}$ and $F_{2}$.

Match List-$I$ with List-$II$ based on the bond order of the molecules.

List-$I$	List-$II$
$(a)$ $Ne_2$	$(i)$ $1$
$(b)$ $N_2$	$(ii)$ $2$
$(c)$ $F_2$	$(iii)$ $0$
$(d)$ $O_2$	$(iv)$ $3$

Choose the correct answer from the options given below:

The common features among the species $CN^{-}$,$CO$ and $NO^{+}$ are

In which pair,or pairs,is the stronger bond found in the first species?
$(a) \ O_2^-, O_2$
$(b) \ N_2, N_2^+$
$(c) \ NO^+, NO^-$
