• Name the two types of polymerisation

  • Condensation polymerisation
  • Addition polymerisation
• Combustion of hydrogen

  hydrogen + oxygen -> water
• The 4 different monomers that make up DNA polymers are called nucleotides
• Many substances are soluble in alcohols, which makes alcohols useful as solvents
• What gas is produced when carboxylic acid react with carbonates?

  carbon dioxide
• What qualities does the size of the molecules in hydrocarbons affect?

  flammability

  boiling point

  viscosity
• Polypeptide is produced when 2 amino acids react together by condensation polymerisation
• Which letter identifies polypropane?

  B

  
• Cracking is the process by which large hydrocarbons are broken up into smaller, more useful molecules (alkanes and alkenes)
• Alkenes react with hydrogen to make alkanes (hydrogenation)
• Alcohols react with sodium and release hydrogen gas
• When alcohols are added to water, they dissolve and form a neutral solution
• Alcohols release energy, carbon dioxide and water when they burn in air
• Alcohols can be used as solvents and fuels
• Alcohols react with oxidising agents to form carboxylic acids
• Fermentation is the process of the production of ethanol by anaerobic respiration of yeast

  
• ethanol + sodium -> sodium ethoxide + hydrogen
