Choose the frequency of a peak that is most likely to correspond to an C-N stretch in an IR spectrum. A) 3450 cm B) 1720 cm C) 1600 cm D) 1530 cm E) 1200 cm

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)

3. Attached is the IR for one of the compounds you crystallized in this lab. (a) Is this molecule 2- Naphthol, Acetophenone, Aniline or Vanillin? NAME the compound at the bottom of spectrum box. (b) Please identify and assign the major stretching vibrations. 100 Transmittance (%) 50- 4000 3000 1672 7 1666 6 3184 32 3021 50 2975 57 1598 10 2946 67 1690 10 2864 62 1511 10 2848 82 1455 18 2742 70 1464 32 12 1432 13 1398 52 1389 58 1373 66 1300 7 1266 4 1201 23 1500 Wavenumber (cm-¹) 2000 1172 13 1155 6 1125 24 1031 32 960 84 850 42 827 70 814 60 782 70 733 17 633 27 591 55 555 79 549 79 1000 500

What types of transitions are usually observed in UV spectra?

How does H-nmr shift work ? like how do i know which line goes where ?

Identify which functional groups are suggested by the signals indicated by each of the arrows. Include whether the signal is due to a stretching vibration or a bending vibration.
