Question
Description acceptable. A researcher performing a Swern oxidation may experience this sensation if the reagent that’s supposed to react with oxalyl chloride in the first step is spilled on their bare skin. For 10 points each:
[10h] Name this sensation that occurs following the formation of a disulfide bond between eliminated allin molecules to form allicin.
ANSWER: garlic taste [accept descriptions of someone thinking that they taste the flavor of garlic; accept garlic smell; prompt on smell or taste by asking “what specific thing is being smelled or tasted”; prompt on smell or taste with any type of subjective quality, i.e. “umami taste” or “bad smell”]
[10m] This polar aprotic solvent causes people to taste garlic when absorbed through the skin after its central sulfur is released. The aforementioned Swern oxidation begins by “activating” this molecule.
ANSWER: DMSO [or dimethyl sulfoxide]
[10e] DMSO’s chemical structure is essentially the same as this molecule, except with a central sulfur instead of a central carbon. This simplest ketone is generally used to clean lab glassware and remove nail polish.
ANSWER: acetone [or 2-propanone or propan-2-one or dimethyl ketone]
