Questions and Answers

Which of the following statements about thiol structure is true?

  • Thiol structure is R-CHO
  • Thiol structure is R-SH, with an alkyl group joined to a sulfanyl group. (correct)
  • Thiol structure is R-SO2
  • Thiol structure is R-OH
  • What is the reason behind the longer C-S bond length compared to C-O bond length?

  • Oxygen is a bigger element than sulfur.
  • Oxygen is a heavier element than sulfur.
  • Sulfur is a smaller element than oxygen.
  • Sulfur is a bigger element than oxygen. (correct)
  • What is the method of producing thiols?

  • Heating a halogenoalkane in a solution of sodium chloride
  • Heating a halogenoalkane in a solution of sodium sulfate
  • Heating a halogenoalkane in a solution of sodium hydrosulphide (correct)
  • Heating a halogenoalkane in a solution of sodium hydroxide
  • Study Notes

    • Thiol structure is R-SH, with an alkyl group joined to a sulfanyl group.
    • C-S bond length is longer than C-O bond due to sulfur being a bigger element.
    • Thiols have lower boiling points and solubility in water compared to alcohols of the same molecular weight.
    • S-H bonds in thiol are weaker than O-H bonds in alcohol.
    • Thiols are produced through a similar method as ethers and alcohols.
    • Sulphur anions are superior nucleophiles compared to oxygen atoms.
    • Thiols are produced when a halogenoalkane is heated in a solution of sodium hydrosulphide.
    • Thiols have a minor relationship through hydrogen bonding with water and among themselves.
    • Thiols have relatively lower boiling points.
    • Thiols have lower solubility in water and other polar solvents.
