Chemistry Exam
Five Types of Reactions
(First Year Chemistry)
1)
2)
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.

Single Replacement Reaction
3)
•

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.

Five General Types of Reactions
4)
Double Replacement Reaction

5)
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
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.
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.
