plese don't handwritten solution... What MS resolving power is needed to fully resolve the C8H8NO2 and C7H6N2O2 ions (at the base peaks)?
Complete the following answer using the data provided here: Molecular formula: C4H8O2 Important IR data (cm-1): 3280 (broad); 2980-2730 (many); 1690; 1254 All 1H NMR data (ppm, splitting, integration): 11.0 ppm (s), 1; 2.57 ppm (m), 1; 1.07 ppm (d), 6 1. Sketch out a 1H NMR spectrum showing peak locations and peak splitting on a ppm scale for the data provided above. Include the data labels above in your spectrum, but do not show integration lines. 2. draw the most proper line bond structure for the data given above
Please fully annotate this IR spectrum in the picture below, no need to annotate the fingerprint region (400-1500 cm-1). Thank you so much!!
A H1 NMR signal is observed at 117.0 Hz (downfield of TMS) on a 1.20×102‑MHz instrument. a) What is the observed chemical shift in parts per million (ppm)? Chemical shift is ppm b) What is the chemical shift, in parts per million (ppm), if the sample is analyzed with a 60.0‑MHz instrument? Chemical shift is ppm c) Where will the proton signal appear, in hertz, if the sample is analyzed with a 60.0‑MHz instrument?
interpret NMR spectra and report NMR data stating, in this order: nucleus (1H or 13C), solvent, machine frequency, peaks in order from high to low chemical shift including multiplicity, coupling constants and integration
