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

How many nodal planes are present in the following MO's (Taking Z-axis as the internuclear axis) (i) sigma ls (ii) sigma^(**) ls (iii) sigma2p_(z) (iv) sigma^(**)2p_(z) (v) pi 2p_(y) (vi) pi^(**)2p_(x) or pi^(**)2p_(y) Give the number of electrons which occupy the bonding orbitals in H_(2)^(o+) H_(2) and O_(2)^(o+) (c ) Why N_(2) has greater bond dissociation energey than N_(2)^(o+) whereas O_(2)^(o+) has greater bond dissociation energy than O_(2) .

State the bond order and indicate whether the species is paramagnetic (i) B_(2) (ii) C_(2) (iii) N_(2) (iv) O_(2) (v) Br_(2) (vi) CI_(2)^(o+) Which of the following molecules has the highest bond order (i) Ne_(2) (ii) F_(2) (c) Explain why N_(2) has a greater dissociation energy than N_(2)^(o+) , whereas O_(2) has a lower dissociation energy tnan O_(2)^(o+) (b) The bonding sigma 2s orbital has a higher energy than the antibonding sigma^(**) 1s orbitals Why is the former a bonding orbital while the latter is an antibonding .

N_(2)^(+) has greater bond dissociation enthalpy than N_(2) molecule.

(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. Assign reason :
