Quizplus · Accepted Answer

When propanthiol (also known as 1-propanethiol) ionizes in water, it loses a hydrogen ion (H+) from the thiol group (-SH) to form a thiolate anion (CH3CH2CH2S-). The anion then undergoes a reaction with a water molecule to form a hydroxide ion (OH-) and a protonated thiolate anion (CH3CH2CH2S-H+). Finally, two protonated thiolate anions can undergo a disulfide bond formation reaction to form the product CH3CH2CH2S-SCH2CH2CH3. This is equivalent to the third option (C) provided, which is the correct answer. The other options involved incorrect products or incorrect mechanisms.
