CARACTERISTICS OF
ORGANIC
COMPOUND AND
THEIR USES

16. OBJECTIVES
At the end of this lesson, the students should be able to:
1. Describe the special nature of carbon
2. Observe the characteristics of
common organic compound
3. Relate this characteristics to their
uses

17. Element for the Day

18. What can you say about the
element carbon?
Carbon known since ancient times. It
was first recognized as an element in
the second half of 18th century.
A.L.Lavoisier proposed carbon in
1789 from the Latin carbo meaning
charcoal.

19. Organic Compound
• Organic compound are group of
compounds that contain the element
carbon.
• Organic chemistry is study of living
things

20. Biology – study of life. Rather
organic chemistry takes a look at
what composes the living things.

22. Characteristics of Common
Organic Compound
Discussion
Key word:
• Odor
• Volatility
• Viscosity
• Flammability

23. Let’s Collaborate!
Characteristic of Common
Organic Compound
Materials:
Kerosene calculator
Lubricating oil/cooking oil matches
Diesel oil 4 pcs. bond paper
Ethyl alcohol 25ml grad. cylinder
4 medicine dropper 4 test tube
Stop watch 4 bottle crown
4 pieces beads/marbles

24. Precautionary measure/Caution:
1. Follow the procedure carefully
because you are about to use
flammable substances.
2. Prepare wet rags to be used in case of
fire
3. Wear lab gown, face mask before
performing the following procedure.

25. Procedures:
1. a. With your group, used the table below to
record your data from this activity.
Materials Odor Phase Viscosity
(average
time it takes
the marble to
reach the
bottom)
Volatility
(the time it
takes the
liquid to
evaporate)
Flammability
(average
time it takes
the material
to burn
completely)
Kerosene
Lubricating
oil
Diesel oil
Ethyl alcohol

26. b. Place 15 ml of each liquid in the four identical test tubes
and label each test tube according to the liquid contains.
c. Observe the materials and write the phase and odor of
the materials on the table.
2. Testing the viscosity of the materials
a. Fill the test tube with the first liquid, drop one plastic
beads or marble and cover it tightly with a cork.
b. Invert the test tube so that the bead falls and touches
the cork.
c. Quickly turn the test tube in an upright position.
Determine the time it takes to fall and reach the bottom
of the test tube.

27. 3. Testing the Volatility of the materials
a. Using the medicine dropper , put two drops of
each liquid materials on the separate pieces of
bond paper. You and your group mates should
do this at the same time and place it on the
armrest.
b. Record the time it takes the paper to get dry.
This equivalent to the time it takes the liquid to
completely evaporate.

28. 4. Testing for Flammability of materials
a. Prepare the 4 bottle crowns and them place a cotton
balls in each crown.
b. Wet the cotton balls with 10 drops of the liquid
materials.
c. Ignite each wet cotton using lighted match stick.
d. Record the time it takes each cotton to burn
completely.
e. Repeat a, b, c, d four time so that you will have five
trials per liquid materials.
f. Compute the average time it takes each set up to burn
completely.

29. Guide questions:
1. Which materials is most viscous? What are the
common uses of viscous materials?
2. Which materials is flammable? In what ways
are these materials used?
3. Which liquid materials have strong odor?
4. Why is it important to know the properties of
these kinds of organic compound?

32. HOTS!
Base on the characteristic and properties of
organic compound, What are some uses of
organic compound?

33. Overview
Characteristic of Common Organic
Compound
I. Phase of matter is the physical state of the
materials. This describes the physical property of
matter it is solid , liquid or gas
II. Viscosity is a measure of a fluids resistance to flow.
If the viscosity is high, the flow of the liquid is slow
or the liquid is thick.
III. Volatility is the measure of the tendency of
substance to evaporate or turn into gaseous state.
IV. Flammability is the measure of how materials easily
to burns.

34. - Every kind of organic compound
has specific properties or
characteristics. Although these
compound may show similar
properties in some properties, these
compound do not have the exactly the
same properties.

35. Assessment
True or False: Write pak if the statement is True and
write ganern if the statement is False.
1. Volatility is the resistance of a liquid materials to
flow.
2. Kerosene is more viscous than lubricating oil.
3. Some uses of alcohol is used as antiseptic.
4. Organic compound is a branch of chemistry that
study the carbon containing carbon compound
only.
5. Carbon contain four valence electron that ready to
form covalent bond.

experiment and provide caption for each
picture.
Reflection:

37. Assignment:
1. Research the twelve kinds of organic
compound.
2. Identify the uses of each organic
compound.
3. Advance study on how organic compound
named.
