Minds-On
Minds-On
In Topics 1-4, you learned about all of the organic families that comprise organic compounds. In the Topic 5 and 5, we will focus on the reactions that result in the formation of these compounds and their practical applications.
Upon completion of Topic 5 and 6, you will be able to:
describe different types of organic reactions
predict and correctly name the products of organic reactions
Millions of reactions take place everyday in the trillions of cells in your body. Since living organisms are composed of organic compounds, many of the reactions we will discuss in this lesson also occur in the cells of your body.

Combustion Reactions
Combustion Reactions
There are two types of combustions reactions – complete and incomplete. Both reactions involve a hydrocarbon reacting with diatomic oxygen gas.
Complete Combustions (excess oxygen present)
Complete Combustions (excess oxygen present)
In a complete combustion, when a hydrocarbon reacts with oxygen, the products are always carbon dioxide (CO2), water (H2O), and energy.
hydrocarbon + O2 → CO2 + H2O + energy
hydrocarbon + O2 → CO2 + H2O + energy
Examples of Complete Combustion Reactions
Examples of Complete Combustion Reactions
C5H12 + O2 → CO2 + H2O + energy
C2H5OH + O2 → CO2 + H2O + energy
Incomplete Combustions (limited oxygen present)
Incomplete Combustions (limited oxygen present)
In an incomplete combustion, when a hydrocarbon reacts with oxygen, the products are always carbon (C), carbon monoxide (CO), carbon dioxide (CO2), water (H2O), and energy.
hydrocarbon + O2 → C + CO + CO2 + H2O + energy
hydrocarbon + O2 → C + CO + CO2 + H2O + energy
Examples of Incomplete Combustion Reactions
Examples of Incomplete Combustion Reactions
C3H8 + O2 → C + CO + CO2 + H2O + energy
CH3OH + O2 → C + CO + CO2 + H2O + energy
Addition Reactions
Addition Reactions
The double bond of an alkene is broken and atoms are added to each carbon.
i) Addition reactions with hydrogen (H2)
i) Addition reactions with hydrogen (H2)
Predict the product(s) of the following reaction:
ii) Addition reactions with water (H2O)
ii) Addition reactions with water (H2O)
Predict the product(s) of the following reaction:
iii) Addition reactions with halogens (F2, Cl2, Br2, I2)
iii) Addition reactions with halogens (F2, Cl2, Br2, I2)
Predict the product(s) of the following reaction:
Elimination Reactions
Elimination Reactions
A double bond is formed by removing atoms from two carbons.
An elimination reaction is the opposite of an additional reaction.
Thus, when removing atoms from the organic compound, you can remove:
Water (H2O or HOH)
Hydrogen (H2)
Halogens (F2, Cl2, Br2, I2)
i) Elimination, Removing Water
i) Elimination, Removing Water
Predict the product(s) of the following reaction:
ii) Elimination, Removing Hydrogen and a Halogen
ii) Elimination, Removing Hydrogen and a Halogen
Predict the product(s) of the following reaction:
