Identify the starting material: The structure shown is a disulfide, specifically a dialkyl disulfide, where two isopropyl groups are connected by a disulfide bond (S-S).
Recognize the reaction conditions: The reaction involves zinc (Zn) and hydrochloric acid (HCl), which are commonly used to reduce disulfides to thiols.
Understand the reaction mechanism: Zinc acts as a reducing agent, breaking the S-S bond in the disulfide and forming two thiol groups. The general reaction is R-S-S-R + Zn + 2HCl -> 2R-SH + ZnCl2.
Determine the product structure: The reduction of the disulfide bond in the given structure will yield two molecules of the corresponding thiol. In this case, the thiol formed is isopropyl thiol, also known as 2-propanethiol.
Name the product: The IUPAC name for isopropyl thiol is 2-propanethiol. However, the problem asks for a different naming convention, which could be 2-methyl-1-propanethiol, matching the options provided.
