    Cards (12)

    • What is the functional group of carboxylic acids?
      -COOH
    • What are the first four members of carboxylic acids?
      Methanoic, ethanoic, propanoic, butanoic
    • How is an ester formed from a carboxylic acid?
      By replacing the -COOH group with a hydrocarbon group
    • What is the structural formula of ethyl ethanoate?
      CH<sub>3</sub>COOCH<sub>2</sub>CH<sub>3</sub>
    • What should be included when drawing displayed formulae for organic compounds?
      • Show all bonds
      • Include bonds in functional groups
      • Represent atoms with their chemical symbols
    • What is the displayed formula of methanoic acid?
      HCOOH
    • Why are alkenes more reactive than alkanes?
      Due to the presence of a double bond
    • What is the structural formula of propanoic acid?
      CH<sub>3</sub>CH<sub>2</sub>COOH
    • What is the structural formula of butanoic acid?
      CH<sub>3</sub>CH<sub>2</sub>CH<sub>2</sub>COOH
    • What is the significance of showing all bonds in displayed formulae?
      It accurately represents the molecular structure
    • How does the structure of an ester differ from that of a carboxylic acid?
      An ester has a hydrocarbon group replacing -COOH
    • What is the displayed formula of ethyl ethanol?
      CH<sub>3</sub>CH<sub>2</sub>OH
