  1. 5.1 Organic Chemistry Objective: to identify organic compounds, and explain their properties and reactions Outcomes: All: I can list some uses of alcohols, carboxylic acids and esters (D/E) Most: I can identify and name alcohols, carboxylic acids and esters (C) Some: I can explain some reactions of alcohols, carboxylic acids and esters (A/B) Keywords: organic compounds, alcohol, carboxylic acid, ester, pH

  2. These are all examples of organic molecules… Can you see what they have in common? What is an organic compound? A ‘backbone’ of CARBON ATOMS bound to hydrogen I can identify and name alcohols, carboxylic acids and esters (C)

  3. Naming Organic Compounds These ones you have met before… Which 2 groups of molecules (homologous series) are they each from? Can you name them? ALKANES -ane C-C ethene ethane ALKENES -ene C=C I can identify and name alcohols, carboxylic acids and esters (C)

  4. Naming Organic Compounds Remember the carbon naming…? methane ethane butane propane I can identify and name alcohols, carboxylic acids and esters (C)

  5. Naming Organic Compounds This one you might know…. ALCOHOL Functional Group -OH ethanol Can you think of any uses of alcohols? fuels What about this one? methanol drinks I can identify and name alcohols, carboxylic acids and esters (C)

  6. Naming Organic Compounds Carboxylic acids This is ethanoic acid. What about this one?

  7. Match the organic compounds to the correct pictures. Write down your answers. 1. alcohol 3. ester 2. carboxylic acid A B D C E -COOH G F -OH H I J K -COO-

  8. Properties & Reactions of Alcohols COMBUSTION Complete the equation: ethanol + oxygen → _________ + _______ Write the balanced symbol equation: carbon dioxide water C2H5OH + O2→ CO2 + H2O 3 2 3 I can explain some reactions of alcohols (A/B)

  9. Properties & Reactions of Alcohols pH7 What is the pH of alcohol in water? What do you observe when sodium is added? What gas is formed? HYDROGEN GAS I can explain some reactions of alcohols (A/B)

  10. Naming Organic Compounds This one is a CARBOXYLIC ACID CARBOXYLIC ACID - anoic acid -COOH ethanoic acid Can you think of any uses of carboxylic acids? What about this one? vinegar propanoic acid I can identify and name alcohols, carboxylic acids and esters (C)

  11. Properties & Reactions of Carboxylic Acids What do you observe when 1moldm-3 HCl is added to calcium carbonate? What do you observe when 1moldm-3 ethanoic acid is added to calcium carbonate? But slower… What gas is formed? CARBON DIOXIDE GAS pH2-5 What is the pH of carboxylic acid in water? I can explain some reactions of carboxylic acids (A/B)

  12. Reactions of Carboxylic Acids and Alcohols + ESTER • yl -anoate alcohol c.acid -COO- → ethyl ethanoate I can explain some reactions of carboxylic acids and alcohols (A/B) I can identify and name alcohols, carboxylic acids and esters (C)

  13. Use of esters Can you think of any uses of esters? perfumes flavourings biofuels I can list some uses of alcohols, carboxylic acids and esters (D/E)

  14. Match the organic compounds to the correct pictures. Have you changed your mind? 1. alcohol 3. ester 2. carboxylic acid A B D C E -COOH G F -OH H I I can identify (C) and list some uses of alcohols, carboxylic acids and esters (D/E) J K -COO-

  15. How did you do…? 1. alcohol 3. ester 2. carboxylic acid A B D C D E -COOH G F -OH I can identify (C) and list some uses of alcohols, carboxylic acids and esters (D/E) H I J K -COO-
