Problem

 All of the following statements concerning molecular orbital (MO) theory are correct EXCEPT

a. The Pauli exclusion principle is obeyed.

b. Hund’s rule is obeyed.

c. The combination of two atomic orbitals creates one molecular orbital.

d. A bonding molecular orbital is lower in energy than its parent atomic orbitals.

e. Electrons are assigned to orbitals of successively higher energy. 

Solution

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.
