    Answers

      1. IUPAC: propanal; Common: propionaldehyde
      2. IUPAC: 3-pentanone; Common: diethyl ketone
      3. IUPAC: 3-methyl-2-butanone; Common: isopropyl methyl ketone
      1. 2-hexanol
      2. 2-propanone
      1. IUPAC: 3-methylbutanoic acid; Common: β-methylbutyric acid
      2. IUPAC: 3,4,4-trimethylpentanoic acid; no common name
      3. IUPAC: 4-bromobutanoic acid; Common: γ- bromobutyric acid
    1. Propanoic acid because both molecules can form hydrogen bonds, but this compound is more polar. As the carbon chain length increases because dipole forces become less important and dispersion forces become more predominant.
      1. ethyl hexanoate
      2. ethyl benzoate
      3. ethyl 3-methylhexanoate
    1. Propanoic acid because it can form hydrogen bonds with water.
      1. common: propionamide; IUPAC: propanamide
      2. common: α-methylbutyramide; IUPAC: 2-methylbutanamide
    1. N-methylethanamide because it can form hydrogen bonds with water.
