AP Chemistry Unit 2 Practice

Instructions

  1. Choose a topic, then start. Mixed review includes all seven topics.
  2. Select one answer, or enter a number and choose its unit. For a count, choose count; for a ratio, choose no units.
  3. Submit once per question. Read the explanation, then continue. Your score counts correct answers; a significant figure note does not remove a point.
  4. At the end, Try again shuffles the questions and answer choices. Choose another topic to build a new set.

Choose one topic for six questions, or Mixed review for all 42. Read the feedback after each answer.

No timer. Use scratch paper and a calculator. Bonding reference values are below.

Reference

Bonding reference

Valence electrons: H 1, B 3, C 4, N 5, O 6, F 7, Cl 7. Add one electron for each negative charge; subtract one for each positive charge.

Formal charge = valence electrons − nonbonding electrons − half the bonding electrons. Report formal charge in units of e, the elementary charge.

Coulomb's law: attraction magnitude is proportional to the charge product divided by distance squared. A potential energy curve has its equilibrium bond length at the minimum.

Each single, double, or triple bond counts as one electron domain. Include lone pairs when finding electron geometry.
