3. 4.1
Carbon Compounds

4. What are carbon
compounds?
Compounds that contains
carbon atoms combine with
other elements such as hydrogen
and oxygen

5. Carbon compounds
Organic compounds Inorganic compounds
From living things Not from living
things
Examples
• sugar
• protein
• starch
Examples
• Carbon dioxide
• Sodium carbonate
• Chalk

7. Hydrocarbon
What are hydrocarbons?
CarbonHydrogen
Compounds which consists
of only carbon and hydrogen
atoms only

8. Examples
Methane, CH4 Petrol
Is glucose, C6H12O6
a hydrocarbon?
Why?

9. Sources of Hydrocarbonns

10. 4.2 Alcohol

11. Is alcohol an
organic
compound?
Why?

12. Alcohols
Organic compounds
Contain CHO
Examples
Methanol
Ethanol
Propanol

13. The Production of Ethanol
glucose + yeast → ethanol + Carbon
dioxide
Fermentation

14. Fractional
Distillation

15. Properties
of Alcohol
÷
Colourless
liquid
Soluble in water/
miscible in water
Low
boiling point
Burn with a blue
flame
Reacts with organic acid
to form ester

16. ethanol + Organi
c acid
→ ester + water
Esterification
Concentrated sulphuric acid
Sweet smell

17. Uses of Alcohols
fuels solvents
alcoholic
drinks
esters
disinfectants cosmetics
