WebPeak around 3000 − 3100 cm - 1 for the sp A 2 = C − H stretch and peak at around 1670 cm-1 corresponding to the carbonyl sp A 2 C = C stretching. So the compound has an alkenic group. The other peaks are for C-C and C-H single bonds. Therefore, The IR thus supports presence of alkenic double bond. View the full answer Step 2/3 Step 3/3 Final answer WebIR cameras have detectors that absorb a narrow band of infrared radiation in the electromagnetic spectrum and transform it into a 2-dimensional temperature field.
