An Intiative by Sri Chaitanya

The bond length of $O_{2}^{+}$ is shorter than $O_{2}$ due to removal of electron from $π^{*}$

$H_{2}^{+}$ is more stable than $H_{2}^{-}$ although both have same bond order

Magnetic moment of NO is greater than $O_{2}$

The ionisation energy of $N_{2}$ is greater than N

answer is B, C, D.

Detailed Solution

(a) NO has 1 unpaired electron while $O_{2}$ has 2 .

(c) The first ionization energy of N2 is more than the first ionization energy of atomic nitrogen as the energy of bonding molecular orbitals of nitrogen molecule are lower than the atomic orbital of nitrogen atom.
(d) $H_{2}^{+}$ is more stable because it has less number of antibonding electron.
