Give answer of following questions.
$(i)$ Give molecular orbitals and type form by $\mathrm{LCAO}$ from $2{\rm{s}},2{{\rm{p}}_{\rm{x}}},2{{\rm{p}}_{\rm{y}}}$ and $2{{\rm{p}}_{\rm{z}}}$
$(ii)$ ${\rm{L}}{{\rm{i}}_2},{\rm{B}}{{\rm{e}}_2},{{\rm{C}}_2},{{\rm{N}}_2},{{\rm{O}}_2}{\rm{,}}{{\rm{F}}_2}$ for these molecule give energy other.
If ${N_x}$ is the number of bonding orbitals of an atom and ${N_y}$ is the number of antibonding orbitals, then the molecule/atom will be stable if
The correct order of the $O-O$ bond length in $O_2$ , $H_2O_2$ and $O_3$ is
