<p>When I took the SAT in Chemistry, there were no direct questions on any of those topics (certainly no quantum numbers). However, you should have a conceptual understanding of bonding and how it affect a molecule. For example, knowing that graphite is good as a lubricant and conducts electricity follows from its unhybridized p orbitals existing between its sheets.</p>
