LESSON PLAN

Education Level                : Senior High School
Subject                              : Chemistry
Grade/ Semester                : X / II
Topic                                 : Hydrocarbons and Petroleum
            Sub Topic                          : Reaction of carbon compound
Academic Year                 : -
Time Allocation                : 2 x 45 minutes
Standard Competence       : Comprehends organic compound characters based on functional group and macromolecules
Basic Competence            : Classifies hydrocarbon compound based on the structure and the relationship with compound character
I.             INDICATOR
1.Describe the examples of hydrocarbon compounds reactions
2.Explain formulates reaction of alkane, alkene, and alkyne simple compounds

II.          PURPOSE OF LEARNING
1.Students of Senior High School Class X semester 2 can describe the  examples of hydrocarbon compounds reactions
2.Students of Senior High School Class X semester 2 can explain the formulates reaction of alkane, alkene, and alkyne simple compounds

III.       LESSON MATERIAL
Hydrocarbon compounds such as alkanes, alkenes, and alkynes can undergoes the chemical reactions with other substances and form the new substances. For example, alkanes which are paraffin (difficult to react) can undergoes the chemical reactions such as combustion, substitution, and cracking, while alkenes and alkynes can react to form other compounds among other through the combustion, addition, and polymerization.
1.      Complete combustion reaction of propane gas.
C3H8 + 5O2 à 3CO2 +4H2O
2.      Substitution reaction of methane to produce chloromethane or methyl chloride ( a colorless and poisonous gas used as a refrigerant and local anesthetic). This reaction is also called chlorination.
CH4 + Cl2 à CH3Cl + HCl
3.      Cracking reaction of ethane to produce ethylene or ethane and hydrogen gas used in industries.
C2H6                    C2H4 + H2
4.      Addition reaction ethane and water to produce alcohol
CH2 = CH2 +H2O à CH3            CH2OH
5.      Combustion reaction ethene to produce carbon dioxide and water
C2H4 +3O2 à 2CO2 +2H2O
6.      Addition reaction propene and HCl to produce 2-chloropropane
CH2 = CH            CH3 + HCl à CH3           CHCl            CH3
7.      Polymerization reaction of ethane or ethylene to produce polyethene or polyethylene
n CH2 = CH2 à (            CH2             CH 2           )n
8.      Reaction between ethyne and hydrogen gas to produce ethane.
C2H2 +2H2 à C2H6

IV.       LEARNING MODEL
