- Will acetylene react with sodium hydride according to the following equation to form a salt and hydrogen, H2? Using pKa values given in Table 4.1, calculate Keq for this equilibrium.arrow_forwardThe following pKa values have been measured. Explain why a hydroxyl group in the para position decreases the acidity while a hydroxyl group in the meta position increases the acidity.arrow_forwardExplain this statement: Although 2-methoxyacetic acid (CH3OCH2COOH)is a stronger acid than acetic acid (CH3COOH), p-methoxybenzoic acid(CH3OC6H4COOH) is a weaker acid than benzoic acid (C6H5COOH).arrow_forward
- What is the best rationale for the difference in acidity in acetone and diethyl ether? A. The more acidic compound has a hydrogen attached to a more electronegative atom B. The more acidic compound has a hydrogen attached to a larger atomic radius atom C. The more acidic compound has a more stable conjugate base because of addition resonance structures stabilizing the charge D. The more acidic compound has a stronger molecular dipole that increases the polarization of the acidic hydrogen E. The more acidic compound has a greater amount of s-character in the acidic bond.arrow_forwardCalculate the Ka's for the following acids: (a) Citric acid, pKa = 3.14 (b) Tartaric acid, pKa = 2.98arrow_forwardSuppose you have a mixture of these three compounds. Devise a chemical procedure based on their relative acidity or basicity to separate and isolate each in pure form.arrow_forward
- 18-28 Arrange these compounds in order of increasing acidity: benzoic acid, benzyl alcohol, phenol.arrow_forwardWhat is the relative trend in acidity and pKa of the two compounds? a. Structure I is the most acidic, and Structure I has the highest pKa. b. Structure I is the most acidic, and Structure I has the lowest pKa. c. Structure II is the most acidic, and Structure I has the highest pKa. d. Structure II is the most acidic, and Structure I has the lowest pKa.arrow_forward
