Question

please answer question

These questions relate to the lectures about M.O. Theory and Term Symbols. 1. Prepare and label a molecular orbital energy level diagram (M.O. diagram) for the hydrogen molecule, H. Sketch the general shapes of the MOs formed. Appropriately shade the phases on the MOS.

Answer 1

1. 2 H atoms make hydrogen molecule (H2).

2. 1s orbitals of both linearly combined (LCAO) to give 2 molecular orbitals.

3. One molecular orbital which is formed by constructive overlapping called bonding molecular orbital and overlapping takes place head on, forms sigma bonding molecular orbital sigma 1s, low energy orbital.

4.Other high energy molecular orbital which is formed by distructive overlapping called anti-bonding molecular orbital and overlapping takes placeside wise, forms sigma antibonding molecular orbital sigma* 1s,High energy orbital.

5. 1 electron from each in 1s orbital of H, therefore 2 electrons after formation of molecular orbitals will be occupied in 1s sigma bonding M.O.

threrefore config. will be sigma_b 1s² sigma^_* 1s⁰
