Ok, so a "student" was given the IR spectra below and selected the molecule shown as the one that matched it, however, there was a better answer available. 1a) In addition to the sp3 C-H stretches present in the spectra, what other major functional group does the spectra show? 1b) What details) tipped you off to the identity of the correct functional group? 1c) How would the spectra of the "student answer molecule below differ from the spectra shown? 100 CHO ALLEINELLINGNAL 4000 2000 3000 REVENUER "Student answer" HC-C-(CH-OH
