Find out the bond order of :
(a) `H_2` (b) `H_2^(+)` (c) `He_2` (d) `Li_2` (e) `Be_2` (f) `B_2`

Explanation

To find the bond order of the given molecules, we will use the Molecular Orbital Theory (MOT). The bond order can be calculated using the formula:

\[ \text{Bond Order} = \frac{(N_b - N_a)}{2} \]

where \(N_b\) is the number of electrons in bonding molecular orbitals and \(N_a\) is the number of electrons in anti-bonding molecular orbitals.
