Answer #1

pKa of ortho chloro phenol = 8.52

reference : Drahonovsky J, Vacek Z; Collect Czech Chem Commun 36: 3431-40 (1971)

hence ortho chloro phenol will predominate , and will be approximately 10 times it's conjugate base.

Specify the reagents (an acid and its conjugate base or a base and its conjugate acid)...
Specify the reagents (an acid and its conjugate base or a base and its conjugate acid) and the concentration of each reagent needed to prepare buffer solutions having the listed pH values. NOTE: The optimum buffer solution is one with equal concentrations of the weak acid (weak base) and its conjugate base (conjugate acid). Under these conditions, the pH of the solution is equal to the pKa (pKb). So the best reagent for each of the solutions below is one...

When a solution contains a weak acid and its conjugate base or a weak base and its conjugate acid, it will be a buffer solution. Buffers resist change in pH following the addition of acid or base. A buffer solution prepared from a weak acid (HA) and its conjugate base (A−) is represented as HA(aq)⇌H+(aq)+A−(aq) The buffer will follow Le Châtelier's principle. If acid is added, the reaction shifts to consume the added H+, forming more HA. When base is...

When 1-iodo-1-methylcyclohexane is treated with NaOCH2CH3 as the base, the more highly substituted alkene product predominates. When KOC(CH3)3 is used as the base, the less highly substituted alkene predominates. Give the structures of the two products and offer an explanation. The major product which results when 2-chloropentane is heated in sodium iodide is an ether. Show and name the mechanism by which this ether forms.
