Chapter 10, Problem 7

Sketch the antibonding molecular orbital that results from the linear combination of two 1s orbitals. Indicate the region where interference occurs and state the type of interference (constructive or destructive).

Verified step by step guidance
1
Start by considering two hydrogen atoms, each with a 1s atomic orbital, coming together to form a molecule.
When these 1s orbitals overlap, they can combine in two ways: constructively or destructively.
For the antibonding molecular orbital, focus on the destructive interference, where the wave functions of the two 1s orbitals have opposite signs.
Sketch the antibonding molecular orbital as having a node between the nuclei, where the electron density is zero due to destructive interference.
Label the region between the nuclei as the area of destructive interference, indicating that this is where the electron density is reduced, leading to the antibonding character.
