Which of the molecules in each of the following pairs should have identical IR spectra, and which should have different IR spectra (if only slightly different)? Explain your reasoning carefully.

(a) 3-pentanol and (±)-2-pentanol (b) (R)-2-pentanol and (S)-2-pentanol (c) OH and -OH (Assume you could determine the IR spectra of each conformation individually.)
