20. Some alcohols undergo rearrangement or other unwanted side reactions when they dehydrate in acid. Alcohols may be dehydrated under mildly basic conditions using phosphorus oxychloride (POCI3) in pyridine. The alcohol reacts with phosphorus oxychloride much like it reacts with tosyl chloride, displacing a chloride ion from phosphorus to give an alkyl dichlorophosphate ester. The dichlorophosphate group is an outstanding leaving group. Pyridine reacts as a base with the dichlorophosphate ester to give an E2 elimination. Propose a reasonable mechanism for the dehydration of 2- methylcyclohexanol by POCl 3 in pyridine.

A purified protein is in a HEPES (N-(2-hydroxyethyl)piperazine-N-(2-ethanesulfonic acid)) buffer at pH 7 with 600 mM NaCl. A 1 mL sample of the protein solution is placed in a tube made of dialysis membrane and dialyzed against 2.0 L of the same HEPES buffer with 0 mM NaCl. Small molecules and ions, such as Na, Cl, and HEPES, can diffuse across the dialysis membrane, but the protein cannot. Once the dialysis has come to equilibrium, what is the concentration of NaCl in the protein sample? Assume no volume changes occur in the sample during the dialysis. [NaCI] = mM If the original 1 mL sample were dialyzed twice, successively, against 200 mL of the same HEPES buffer with 0 mM NaCl, what would be the final NaCl concentration in the sample? [NACI] = mM
