B. Learning Material:

1) Hydrocarbon Compound ( Hydrocarbon Compound)

Hydrocarbon compounds consisting of carbon and hydrogen. Part of

chemistry that addresses the chemistry of carbon compounds called

hydrocarbons. First hydrocarbon is called hydrocarbon chemistry,

because the compounds can be obtained only from the living body and

can’t be synthesized in the factory. However, since Friedrich Wohler in

1928 successed to synthesize urea (a compound that found in urine) from

an in hydrocarbon compound, ammonium cyanates by heating that

ammonium cyanates ( NH4OCN).

Once the success of Wohler is known, many are other scholars who are

trying to make carbon compounds from in hydrocarbon compounds.

Gradually, the theory about the power of life is lost and people just use

the hydrocarbon chemistry as a name without suitable it to the real sense.

2) Showing Carbon and Hydrogen Element in Hydrocarbon Compound

(Hydrocarbon Compound).

Hydrocarbon is a compound consisting of carbon (C) and elemental hydrogen

(H). The whole hydrocarbons having carbon chain and hydrogen atoms are

bonded to the chain. The existence of the elements carbon, hydrogen, and

oxygen in carbon compounds can be demonstrated by heating the carbon

compounds. The existence of the elements carbon and hydrogen in sample of

hydrocarbon compound also be addressed with a simple experiment, namely the

combustion testing. Combustion of hydrocarbon samples will change the C into

CO2 and H into H2O. CO2 gas because it can turbid the limewater, while water

can identified with cobalt paper because the water change color cobalt paper

7

from blue to pink. The presence of oxygen element in organic sample usually not

show in specifically, but can know from the dispute between mass of sample

with amount mass of carbon, hydrogen and the others.

1. Objective

To identify the elements of C and H in on hydrocarbon compound.

2. Basic Theory

The presence of element C, and H in hydrocarbon compound can define with

combustion reaction that form carbon and hydrogen elements. Combustion of

hydrocarbon compound perfectly produce CO2 gas, while the imperfect

combustion of hydrocarbon compound form carbon with brownish black color.

If the result of vapor can make cobalt paper become pink it means that in that

compound consist of hydrogen element so that compound is hydrocarbon

compound.

Exercise 1

Guided Task:

1) Write the formula of compound that we use in the experiment!

Sugar : C12H22O11

2) Based on observation, answer this question below:

a. Changing in test tube that contain of sugar :

Answer: the sugar in the test tube changing into brownish black color.

b. Changing of Cobalt Paper :

Answer: firstly cobalt paper has blue color but after put into test tube

become pink

3) Conclusion

Answer:

Identification of carbon in hydrocarbon compound can do with

combustion of hydrocarbon compound so we get carbon in charcoal

form with brownish black color.

Identification of hydrogen in hydrocarbon compound can do with

combustion of hydrocarbon compound so we get vapor from the

combustion that can make cobalt paper changing from blue become

pink.
