Hunds rule states that:

A Electrons pair first

B Electrons fill orbitals of equal energy singly with parallel spins before pairing

C Higher energy orbitals fill first

D All orbitals hold 2 electrons

✓ Correct Answer: Option B

Hunds rule: one electron in each degenerate orbital before pairing (maximizes spin multiplicity). Minimizes electron repulsion.

💡 Why is B) the correct answer?

The correct answer to the question "Hunds rule states that:" is Option B: Electrons fill orbitals of equal energy singly with parallel spins before pairing.

The other options — A) Electrons pair first, C) Higher energy orbitals fill first, D) All orbitals hold 2 electrons — are incorrect for this DAT Exam Prep question. As explained above: Hunds rule: one electron in each degenerate orbital before pairing (maximizes spin multiplicity). Minimizes electron repulsion.
