exhibits hydrogen bonding, which requires more energy to overcome than the dipole-dipole forces in PH3cap P cap H sub 3 5. The "Low-Hanging Fruit"

Expect to draw or interpret "dots in a box." Practice representing physical vs. chemical changes using circles to ensure you aren't losing atoms (Conservation of Mass). 3. Math Without a Calculator The Multiple Choice section is no-calculator . Estimation is your best friend: If you see , treat it as

Remember that the slow step of a mechanism determines the rate law. It’s like a traffic jam; the whole road only moves as fast as the slowest car. Cracking the AP Chemistry Exam

This is the "why" behind everything. If you can explain how polarities and forces (like London Dispersion or Hydrogen bonding) affect boiling points and solubility, you’ve won half the battle.

When answering long-form questions, follow this template to ensure you get full points: exhibits hydrogen bonding, which requires more energy to

Never just say a molecule is "more stable." Instead, say it has "stronger Coulombic attractions" or "more polarizable electron clouds."

Usually, only one point on the entire exam is dedicated specifically to sig figs—don't let them paralyze you, but keep them in mind for the FRQs. It’s like a traffic jam; the whole road

Cite the data provided or the specific intermolecular forces involved. Reasoning: Connect the two. "Because NH3cap N cap H sub 3
