lesson on different organic compounds: Properties

1. Carbon atoms form many
compounds by bonding with
hydrogen atoms and other
elements.

2. Why is it that gasoline is
flammable and acetone
evaporates easily?

5. Which material is
most viscous?
Lubricating oil

6. What are the
common uses of
viscous
materials?

7. Common uses of viscous materials
or liquids are used to lubricate parts
of machines, instruments, or
appliances such as motor of electric
fan; and
protect metals from rusting.

8. Which materials
are flammable?
Kerosene and Ethyl alcohol

9. What are the
common uses of
flammable
materials?

10. Flammable liquids such as kerosene is used as
fuel for lamps (gasera) and portable stove
(kusinilya). Although ethyl alcohol is also
flammable, it is not used as fuel for stoves or
lamps only. It is also used as a component of
biofuels for vehicles, as an ingredient for
liquors, and as a disinfectant.

11. Which liquid
materials have
strong odor and
weak odor?
ethyl alcohol, lubricating oil

12. Why is it important to
know the properties
of these materials?

13. It is important to have
knowledge about the properties
of these compounds so people
will be aware of their behaviour,
uses, and effects on people.

14. Prepared by:

15. Viscosity is a measure of a fluid’s
resistance to flow. If the viscosity
is high, the flow of the liquid is
slow or the liquid is thick.

16. Volatility is the measure of the
tendency of substance to
evaporate or to turn into its
gaseous state.

17. Flammability is the
measure of how easily
a material burns.

18. 1.Ron’s car stopped in the middle of the road. He
found out that his car ran out of fuel. What
organic compound must he buy?
2. Romina told her daughter Cassie to never
play with gasoline. Why do you think she
does not allow her to do it?
