Answer #1

Hydrogen attached to -OH --> most electronegative, must be the one to 190 approx..

peaks at 80, are those 2 Hydrogens attached to benzene ring FAR away of the COH group

peaks at 130 --> 2 hydrogens attached to benzene ring in the MIDDLE away of the COH group

peaks at 140--> 1 hydrogens attached to benzene ring in the NEAREST away of the COH group

    Only need help with 5,6,7 and mechanism FTIR and NMR Spectra After completing a reaction and working up the products, it is still necessary to confirm that the correct product was formed. The most common tools used for this analysis are Fourier Transform Infrared (FTIR) and Nuclear Magnetic Resonance (NMR) spectroscopy. In the virtual laboratory, 'H and C NMR spectra are available. Details on interpreting FTIR and NMR spectra are found in your textbook. Your instructor may or may not...

    NMR IR CAN YOU PLEASE ANSWER AS SOON AS POSSIBLE THANK YOU PLEASE EXPLAIN IT IN DETAIL THANK YOU Experimental Data Only report the IR absorptions that provide diagnosis for the major functional groups. Copies of your spectra will be included in your lab report with this information written on the spectra. However, the information should also be included in the body of the report in a text format similar to the example given below IR cm1: 1735 (C-o); MS:...
