  1. Functional Groups What is the family name?

  2. H H H C C H H H alkanes • Only carbon and hydrogen • All single bonds Q: What should you call cyclic hydrocarbons made up o of just single bonds? A: Cycloalkanes

  3. H H C C H H alkenes • Only carbon and hydrogen • A carbon to carbon double bond Q: What should you call a molecule with two C=Cs? A: A diene

  4. H H C O H H C H H alcohols • Only one oxygen • Has an O-H group • Can classify as 1º/2º/3º according to position of O-H group on carbon skeleton Q: Why are short-chain alcohols so soluble in water? A: They can form hydrogenbonds with H2O molecules

  5. O H phenols • Only one oxygen • Has an O-H group • The O-H group is directly attached to a benzene ring Q: The C6H5- group has a special name. What is it? A: Phenyl

  6. H O H C C H H aldehydes • Only one oxygen • Has a C=O group • C=O group is at the end of carbon chain, so is next door to a hydrogen atom Q: Aldehydes can be easily oxidised to form …? A: Carboxylic acids

  7. H O H H C C C H H H ketones • Only one oxygen • Has a C=O group • C=O group is not at the end of carbon chain, so is next door to 2carbons Q: Ketones cannot easily be oxidised. Why not? A: No hydrogen atom attached to the C=O group.

  8. H O H C C O H H A: CH3COOH(aq) CH3COO–(aq) + H+(aq) carboxylicacids • Has 2 oxygens • Has O-H and C=O groups on the same carbon atom • This -COOH group has to be at the end of a carbon chain (why?) Q: Write an equation showing how ethanoic acid can a act as a (weak) acid.

  9. H O H H C C O C H H H esters • Has 2 oxygens • One oxygen is part of a C=O bond, the other is nextdoor, sandwiched between two carbons Q: This ester can be made by reacting ethanoic acid with a an alcohol. Name the alcohol, and name the ester. A: Alcohol = methanol; ester = methylethanoate

  10. H H H H C C O C H H H H ethers • Has 1 oxygen • No O-H or C=O group • The oxygen is sandwiched between two carbon atoms Q: Why do ethers have much lower boiling points t than their isomeric alcohols? A: No hydrogen bonds between ether molecules (why?)

  11. Family names: cycloalkane alkene primary (1º) alcohol secondary (2º) alcohol tertiary (3º) alcohol phenol aldehyde ketone carboxylic acid ester ether … are you ready? “What family…?” quiz 5 … 4 … 3 … 2 … 1 … GO!
