- Which of the following statements regarding IR spectroscopy is incorrect?In Section 6.2d, we saw that the pK, of an acid is equal to the pH of the solution at which half the acid has dissociated into its conjugate base. UV-vis spectroscopy can be used to measure the relative concentrations involved if the acid or conjugate base absorbs UV-vis light. With this in mind, suppose that a particular acid has a Amax of 312 nm. The figure here shows the absorbance at that wavelength as a function of pH. What is the pk, of the acid? 3 4 6 7 8 10 11 12 pH Absorbance at 312 nm3. Which of the following isotopes are NMR active and explain the reason: ¹H,2H, ¹2C, ¹³C, 14N, 15H, 180. What are the three major information that ¹H NMR provides? Discuss how the information can be used to determine the structure of organic molecules.
