Q79 · CSIR NET Chemistry, June 2016
Paper: CSIR NET June 2016 · Subject: Physical Chemistry · Chapter: Quantum Chemistry · Topic: Hydrogen Atom · Marks: 2 · Difficulty: Medium
In simple molecular orbital theory of hydrogen molecule, bonding $\sigma_g$ and anti-bonding $\sigma_u$ molecular orbitals are constructed as linear combinations of atomic orbitals of two hydrogen atoms. The spatial part of a purely covalent singlet wave function is obtained by
(a)$\sigma_g^2 + \sigma_u^2$
(b)$\sigma_g^2$
(c)$\sigma_g^2 - \sigma_u^2$
(d)$\sigma_g^2 + \frac{1}{2}\sigma_u^2$
