AP Chemistry Full Mock Test 2
AP Chemistry Full Mock 2 emphasises atomic structure, periodic trends, Lewis structures, and molecular geometry. Full-length AP-style exam simulation.
Emphasis: Atomic Structure and Bonding
Full Mock 2 places elevated emphasis on the structural foundations of AP Chemistry — periodic trends, electron configuration, Lewis structures, VSEPR theory, and molecular geometry. While it remains a complete, full-length AP Chemistry-style exam, the question distribution in Mock 2 weights Units 1 and 2 more heavily than average.
Key Areas of Emphasis
Periodic Trends
Mock 2 includes a higher proportion of questions requiring you to rank, compare, or explain periodic trends — atomic radius, ionization energy, electron affinity, and electronegativity. Expect multi-step reasoning questions that ask you to justify trends using nuclear charge and electron shielding arguments, not just recall the direction of the trend.
Lewis Structures and Resonance
Several FRQ and MCQ items in Mock 2 require drawing or interpreting Lewis structures, including molecules with expanded octets, formal charges, and multiple valid resonance structures. Practice selecting the most stable resonance form based on formal charge minimisation and electronegative atom placement.
Molecular Geometry and Polarity
VSEPR-based geometry questions in this mock include both common geometries (tetrahedral, bent, trigonal planar) and less familiar ones (trigonal bipyramidal, seesaw, T-shaped). Polarity questions require you to combine geometry with bond dipole analysis to determine whether a molecule has a net dipole moment.
What to Practise Before Mock 2
- Photoelectron spectroscopy interpretation — identifying elements from PES spectra
- Bond angle prediction for molecules with one or more lone pairs
- Hybrid orbital assignment for all common geometries
- Formal charge calculation for both standard and expanded-octet molecules
FRQ Preparation Tip
Structural FRQs in AP Chemistry are multi-part by design. A single question may ask you to draw a Lewis structure, identify the electron geometry, name the molecular geometry, assign hybridization, and determine polarity. Practise doing all five steps in sequence for diverse molecules before attempting Mock 2.
