Transcript A.P. Chemistry Complexation Reactions

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

Five General Types of Reactions
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.
