Why do you think that most textbooks do not consider a hydrogen bond to be an example of a van der Waals force?
Answer to relevant QuestionsIdentify the conjugate acids and bases in the following pairs of substances: (a) (CH3)3 NH +/ (CH3)3 N (b) +H3N–CH2COOH/+H3N–CH2–COO- (c) +H3N–CH2–COO–/H2N–CH2–COO- (d) ...Define the following: (a) Acid dissociation constant (b) Acid strength (c) Amphipathic (d) Buffering capacity (e) Equivalence point (f) Hydrophilic (g) Hydrophobic (h) Nonpolar (i) Polar (j) Titration Mathematical Show that, for a pure weak acid in water, pH 5 (pKa 2 log [HA])/2. MatheMatical Sketch a titration curve for aspartic acid, and indicate the pKa values of all titratable groups. Also indicate the pH range in which the conjugate acid–base pair +1 Asp and 0 Asp will act as a buffer. If you knew everything about the properties of the 20 common (proteinous) amino acids, would you be able to predict the properties of a protein (or large peptide) made from them?
