We’re being asked to identify which of the given statements is incorrect concerning molecular orbital (MO) theory.


Let’s take a look at each statement one by one:

a. The Pauli exclusion principle is obeyed.

Pauli Exclusion Principle states that no two electrons can have the same set of quantum numbers. Meaning no two electrons can be in the same state.
