Why does `N_2` possess a higher bond order than `N_(2)^(+)` ion?

The bond order in N_(2) ^(-) is

What is the bond order of H_(2)^(-) ion ?

Calculate their bond order N_(2)^-

The calculated bond order in H_(2)^(+) ion is

Why are the bond orders in He_(2)^(+) and He identical?

Explain why N_(2) has a greater bond dissociation energy than N_(2)^(+) while O_(2) has lesser bond dissociation energy than O_(2)^(+).

Why does O_(2)^(2-) possess a larger bond length as compared to O_(2)^(-) ion and O_2 molecule?

Why the alkyl cyanides possess higher boiling points than the corresponding alkyl halides?

With respect to graphite and diamond, which of the statements given below are correct? (1) Graphite is harder than diamond. (2) Graphite has higher electrical conductivity than diamond. (3) Graphite has higher thermal conductivity than diamond. (4)Graphite has higher C-C bond order than diamond.

(a) H_(2)^(+)and H_(2)^(-) ions have same bond order but H_(2)^(-) ion is more stable. Explain. (b) N_(2) has a greater bond dissociation enthalpy than N_(2)^(+) ion hals more bond dissociation enthalpy than O_(2). Why ? (c ) Can we have ahomonuclear diatomic molecule with all its ground state molecular orbitals full of electrons ? (d) When a magnet is dipped in a jar of liquid oxygen, some oxygen clings to it.
