Question

Barry Sharpless popularized an effect named for this compound and the (20[1])word “on,” (20[1])in which chemical reactions happen faster at interfaces. This compound is (20[1])emulsified with mineral oil to form microfluidic droplets. Partition coefficients are measured using a mixture of this compound and octanol. (20[3])This compound has a large contact angle with surfaces that are coated (20[1])in PTFE to make them (*) lipophilic (“LIE-poh-fill-ick”). This compound is excluded from the center of a micelle (10[1])(“MY-sell”) and between (10[1])the leaflets (10[3])of a (10[1])bi·layer (10[2])since it prefers (10[1])to interact (10[2])with (10[1])surfactants’ head groups. (10[3])Long chains (10[1])of hydrocarbons are said to “fear” (10[2]0[1])this compound, (10[6])as its (10[1])hydrogen (10[1])bond network (10[1])only dissolves (10[1])polar molecules. For 10 points, name this universal solvent that forms aqueous phases. ■END■
