  Model answer practice test THREE (C) From the IR spectrum: Presence of a medium peak at 600-700 cm-1 indicative of a Br or a Cl group. Absence of a strong, sharp peak resulting from a C=O stretch at 1810 – 1775 cm-1 (1700cm-1) indicates no carbonyl group, therefore not …

  From the IR spectrum: Absence of a strong, sharp peak resulting from a C=O stretch at 1700cm-1 indicates no carbonyl group, therefore not butanoic acid or methyl propanoic acid. Presence of a broad strong peak at 3300-3600 cm-1 resulting from an OH stretch indicates an OH group therefore supports the other 2 molecules. From the Mass Spec:
