Concept explainers
(a)
Interpretation:
Whether the given reaction favors reactants or products at equilibrium is to be predicted.
Concept introduction:
The replacement or substitution of one
(b)
Interpretation:
Whether the given reaction favors reactants or products at equilibrium is to be predicted Concept introduction:
The replacement or substitution of one functional group with another different functional group in any chemical reaction is termed as substitution reaction. In nucleophilic substitution reaction, nucleophile takes the position of leaving group by attacking on the electron deficient carbon atom.
(c)
Interpretation:
Whether the given reaction favors reactants or products at equilibrium is to be predicted.

- COHSOH(ag) + H2On + CeHsO (aq) + H3O*(a9) Ka= 1.12 x 10-10 (a) Phenol is a weak acid that partially dissociates in water according to the equation above. Write the equilibrium-constant expression for the dissociation of the acid in water. (b) What is the pH of a 0.75 M CaHsOH(ag) solution? (C) For a certain reaction involving CaHsOH(ag) to proceed at a significant rate, the phenol must be primarily in its deprotonated form, C3H5O (eg). In order to ensure that the CsHsOH(aq) is deprotonated, the reaction must be conducted in a buffered solution. On the number scale below, circle each pH for which more than 50 percent of the phenol molecules are in the deprotonated form (CoHsO (aq).

Show all work…arrow_forwardWhat is the equilibrium for the acid-base reaction?arrow_forwardConsider two acids: HCO2H (formic acid, pKa = 3.8) and pivalic acid [(CH3)3CCO,H, pK = 5.0]. (a) Which acid has the larger K? (b) Which acid is the stronger acid? (c) Which acid forms the stronger conjugate base? (d) When each acid is dissolved in water, for which acid does the equilibrium lie further to the right? %3D The pKa values in Table 2.1 span a large range (-7 to 50). The pK, scale is logarithmic. small difference in pK, translates into a large numerical difference, For example, the diffe between the pK, of NH3 (38) and CH2=CH, (44) is six pKa units. This means that NH, is one million times more acidic than CH,=CH,.arrow_forward
