Choose the frequency of a peak that is most likely to correspond to an sp C-H stretch. A) 3450 cm-¹ B) 3300 cm-¹ C) 3100 cm-¹ D) 2800 cm-¹ E) 2200 cm-¹

Which of the following IR frequencies would be expected for ethyl acetate? Select all that apply. - 3395 (broad) ~2980 cm 1 O~1750 cm 1 O-3105 cm-¹ -3135 cm ¹ (extremely broad; overlapping the C-H region)

Identify likely groups and identify likely signals on the IR. (ex. OH, NH, C=C, C-H sp3, aromatic etc)
