Give energy level diagram obtained by over lapping of $2{{\rm{p}}_{\rm{z}}}$ orbitals.And give a diagram of the orbits of that composition.

Give features of Molecular orbital $( \mathrm{MO} )$ theory:

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

When $O _2$ is adsorbed on a metallic surface, electron transfer occurs from the metal to $O _2$. The $TRUE$ statement$(s)$ regarding this adsorption is(are)

$(A)$ $O _2$ is physisorbed

$(B)$ heat is released

$(C)$ occupancy of $\pi_{2 p }^*$ of $O _2$ is increased

$(D)$ bond length of $O _2$ is increased

When ${N_2}$ goes to $N_2^ + ,$ the $N – N$ bond distance ….. and when ${O_2}$ goes to $O_2^ + ,$ the $O – O$ bond distance …….
