- Indicate and circle the most important stretching signal from choices: N-H, O-H, C- - -N, C=O, C-O C8H10O2arrow_forwardWhat is “total luminescence spectrum”? (arrow_forwardIdentify 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.arrow_forward
- Label the IR spectra of the unknown chemical by identifying key stretching frequencies (e.g. O-H, C=C, =C-H)arrow_forwardWavenumbers of prominent peaks/ signal in the spectrum Functional groups present in the unknown (Discussion):arrow_forwardThe black spectra represent that of your extract while the violet one is the spectra for the modified plant extract. Using the figure, answer the following. a. The spectra for plant extract is labelled with 1-5. Name the characteristic bond absorption assignment per item by filling up the table.arrow_forward

- Using the information provided, list the approximate wavenumber ranges corresponding to the bands that you think are from C-H and O-H stretching (no need to distinguish which is which at this point). Which bands do you think result from different C-C and C-O stretching and bending vibrations? C-H and O-H: C-C:arrow_forwardcan someone provide me with the peaks and data from the IR spectrums in a table 1) table 2) table and also explain both of them to me?arrow_forwardList all peaks and multplicity in this NMR Spectrum in addition to what possible compound it can be.arrow_forward
