Properties of organic compounds

lesson on different organic compounds: Properties

1. Carbon atoms form many compounds by bonding with hydrogen atoms and other elements. How do carbon atoms form many organic compounds?

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

4. MATERIAL ODOR PHASE VISCOSITY VOLATILITY FLAMMABILITY KEROSENE BALLOON LIQUID 1:03 sec 5:47 mins 27.40 sec LUBRICATING OIL NO ODOR LIQUID 1:37 sec 8:47 mins 28.30 sec DIESEL OIL PAINT THINNER LIQUID 0.81 ms 1:37 mins 28.55 sec ETHYL ALCOHOL STRONG LIQUID 0. 87 ms 1:48 mins 24.40 sec

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.

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

17. Flammability 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 ? MIND CHECK! 2. Romina told her daughter Cassie to never play with gasoline. Why do you think she does not allow her to do it?
