Thiols are sulfur containing organic compounds. Allyl mercaptan is a small molecule from garlic and responsible for “garlic breath”. Its formula is C3H6S. It has been shown to be the most effective HDAC (Histone deacetylase inhibitors) inhibitor of known garlic-derived organosulfur compounds and their metabolites. Draw all possible isomers with formula C3H6S. Define among the molecules which could be optically active. Which of molecule is allyl mercaptan?

Chemistry A line drawing of a chiral compound is shown below. Draw the structure of either one of its enantiomers. SH Use the wedge/hash bond tools to indicate stereochemistry where it exists. • In cases where there is more than one answer, just draw one. / √ [F ***** CH₂
