Question
Barry Sharpless popularized an effect named for this compound and the word “on,” in which chemical reactions happen faster at interfaces. This compound is emulsified with mineral oil to form microfluidic droplets. Partition coefficients are measured using a mixture of this compound and octanol. This compound has a large contact angle with surfaces that are coated in PTFE to make them (*) lipophilic (“LIE-poh-fill-ick”). This compound is excluded from the center of a micelle (“MY-sell”) and between the leaflets of a bi·layer since it prefers to interact with surfactants’ head groups. Long chains of hydrocarbons are said to “fear” this compound, as its hydrogen bond network only dissolves polar molecules. For 10 points, name this universal solvent that forms aqueous phases. ■END■
