  1. Types of Reactions What you need to know for the A.P. Chemistry Exam

  2. Five Types of Reactions (First Year Chemistry) • Direct combination reaction (synthesis) A + B  AB • A single product is formed from two or more reactants • Decomposition Reaction AB  A + B • The reverse of a synthesis reaction. One reactant breaks into two or more products. YouTube - Elephant toothpaste

  3. Five General Types of Reactions • Single Replacement Reaction A + BX  AX + B • A single element (A) replaces another element (B) in a compound • A single element must be more reactive to replace another element. • Use the Activity Series!

  4. Five General Types of Reactions • Double Replacement Reaction AX + BY  AY + BX • Two compounds switch partners and form two new compounds. • Combustion Reactions • O2 gas reacts with a flammable carbon compound to produce CO2 and H2O C2H5OH + 3 O2 2 CO2 + 3 H2O

  5. What you need to know! • The AP chemistry exam includes combustion reactions with organic molecules. Thus knowing the formula for a given organic molecule will help you write and balance the equation.

  6. Hydrolysis Reactions • A reaction where water is one of the reactants, and a larger molecule is split into two smaller molecules, one of which has the hydrogen from the water and the other has the OH group from the water. • A specific case of the hydrolysis of an amide is the hydrolysis of peptides to smaller fragments or amino acids.
