The prediction of the products of a chemical reaction is a major section on the exam. Writing chemical equations from a verbal description of the reactants is the subject of the Free-Response (Section II), Part B of the exam. Organic and Nuclear Chemistry are of minor significance for the exam.

College Board Performance Objectives:

• Review Sections 3.2 and 4.2–4.4 and in the process try to establish overall rules for writing chemical reactions and for predicting the products given the reactants.
• Go through sections 7.6–7.8 and 22.1 and add to these rules those you've established, be prepared to predict the products of reactions.
• Predict the products of chemical reactions involving oxidation or combustion involving oxygen or proton transfer reactions.
• Identify the types of hydrocarbons.
• Understand and be able to identify structural isomers.
• Know the major function groups.
• Be able to write, balance and predict the products of nuclear reactions.
• Understand the meaning of half-life.

College Board Lab Objectives:

Suggested Labs:

Resources:

• Instructor's Resource Manual (scattered in sections of text)
• Student's Guide (scattered in sections of text)
• Test Bank (scattered in sections of text)
• Instructor's Resource CD (scattered in sections of text)
• "A Review of Reaction Writing", Steve Marsden's Chemistry Home Page, http://www.chemtopics.com/
• A good source of exercises on predicting reactions such as the "Packet of 10 AP Chemistry Exams", published by the College Board.

Pacing Guide:

• Chemical Reactivity and Products of Chemical Reactions—3 days
• Relationships on the Periodic Table with Examples—2 days
• Introductory Organic Chemistry—2 days
• Nuclear Chemistry—1 day
• Block Scheduling
  Subtopics a and b are the major topics in this lesson. They should be treated as a whole and should take at least three blocks of time. If time is short, the other sections are of minor significance and could be omitted. Otherwise, don't spend much more than one block on them together.

Key Words:

Suggested Exercises:
Critical thinking questions and end-of-chapter activities are included in these exercises.

• Give students handouts of Section II, Part B from several previous exams and have them write the chemical equations.

Troubleshooting Tips/Error Traps:

• The more examples the students do, the better they will get at predicting and writing reactions.
