Reactions of Alcohols (T)

• What is the solubility of alcohols in water?

  Alcohols are soluble in water.
• How does the solubility of alcohols change with the number of carbon atoms?

  Solubility decreases as the number of carbon atoms increases.
• What is produced when alcohols react with sodium?

  • Bubbles of hydrogen gas
  • Sodium ethoxide

  Two carbon dioxide molecules.
• How many water molecules are needed to balance the hydrogen atoms in the combustion of ethanol?

  Three water molecules.
• How do you balance the oxygen atoms in the combustion equation for ethanol?

  By adjusting the number of oxygen molecules on the left side.
• What is the balanced equation for the combustion of butanol?

  • 4 carbon dioxide molecules
  • 5 water molecules
