- H 11602003) NaOH H₂O -S BrSi el pOH de una solución es 10, ¿cuánto es el pH?Disulfides are compounds that have S¬ S bonds, like peroxides have O¬ O bonds. Thiols are organic compounds that have the general formula R¬ SH, where R is a generic hydrocarbon. The SH- ion is the sulfur counterpart of hydroxide, OH-. Two thiols can react to make a disulfide, R¬ S¬ S¬ R. If you wanted to convert a disulfide to two thiols, should you add a reducing agent or oxidizing agent to the solution?

The equilibrium idea means that if the reaction is reversible there will be four species in solution at one time, the acid, the base, the conjugate acid, and the conjugate base. Sometimes this is what is required, but at other times we need to choose bases that will completely deprotonate every molecule of acid, i.e. send the reaction completely to the right. These bases will include CH3CH,CH2CH;Li, NaNH2, and LiN(i-Pr)2. Weaker bases will include NaOH, NAOCH3, KOtBu, and NaOCH2CH3. For each of these bases, give the products formed when they react with H2O, then use pKa values to get an idea of the relative base strengths of these compounds. You will provided 7 separate reactions. 3. In CHEM 3112, we will study reactions based on the deprotonation of ketones such as acetone, (CH3)2C=0, which has a pKa of 19.
