(a)
Interpretation:
The mechanism for the given reaction has to be proposed.
Concept introduction:
(b)
Interpretation:
To predict the reside of labeled oxygen in the product when a carboxylic acid is dissolved in isotopically labeled methanol and acid catalyst is added to it.
Concept introduction:
Carboxylic acid reacts with alcohol in the presence of a strong acid to form an ester. Carbonyl oxygen of carboxylic acid gets protonated by the acid resulting in increased electrophilicity of the carbonyl carbon. Alcohol can act as a nucleophile which gets attached to the carbonyl carbon after that tetrahedral intermediate is formed. A proton is removed from alkoxy group (
(c)
Interpretation:
To predict the labeled reside in the product when ester is dissolved in isotopically labeled water(
Concept introduction:
Ester undergoes hydrolysis when dissolved in water with acid. Carbonyl oxygen of ester gets protonated by the acid resulting in increased electrophilicity of the carbonyl carbon. Water can act as a nucleophile which gets attached to the carbonyl carbon of ester after that tetrahedral intermediate is formed. A proton is removed from

- Use the systematic treatment of equilibrium to determine the pH and the concentrations of all species in a saturated aqueous solution of SrF2. Do not include activity coefficients. The solubility of SrF2 is governed by Ksp for the salt, hydrolysis of F- and of Sr2+, and by ion pairing between Sr2 + and F-. PK(SrF2) = 8.58, PK(HF) = 3.17, pkw = 14.00, pk for the formation of (SrOH+) = 13.18, pk for the formation of (SrF+) = 0.14 Show all your work and upload your answers here. 1 - Write the pertinent reactions. 2 - Write mass balance and charge balance equations. 3 - Write the equilibrium constant expressions. 4 - Count the equations and unknowns. 5- If the problem is solvable make suitable approximations and find the concentrations and the pH.arrow_forwardPlease correct answer and don't use hand ratingarrow_forwardHow might you prepare each of the following using a nucleophilic substitution reaction at some step?

(Note: Arsenate = AsO4³-) In the presence of aqueous ammonia, solid Manganese(II) Arsenate becomes more soluble and aqueous tetraamminemanganese (II) ion forms. When solid Manganese(II) arsenate was placed in a 2.00 M solution of ammonia, at equilibrium, 0.308 M of ammonia remains. If the Kf of tetraamminemanganese (II) ion is 250.0, Determine the Ksp of Manganese(II) arsenate Hint: You will have to figure out the Kspf of the overall chemical equation first, then solve for Ksp by using Kf and Kspfarrow_forwardNeed assistance with the following chemistry problem.
