Textbook Question
Chapter 2.7, Problem 2.10P
Write equations for the following acid-base reactions Use the information in Table 2-2 or Appendix 4 to predict whether the equilibrium will favor the reactants or the products.
- a. HCOOH + −CN
- b. CH3COO− + CH3OH
- c. (CH3)2CHOH + NaNH2
- d. NaOCH3 + HCN
- e. HCI + CH3CH2OH
- f. H3O+ + CH3O−
SOLUTION
to (a): Cyanide is the conjugate base of HCN. It can accept a proton from formic acid:
Reading from Table 2-2 formic acid (pKa = 3.76) is a stronger acid than HCN (pKa = 9 22), and cyanide is a stronger base than formate. The products (weaker acid and base) are favored.
