QUESTION 5 The IR, 'H NMR and 1°C NMR spectra of compound P are shown below. The molecular formula for compound P is CsH;NO2. Identify three (3) important absorption peaks on the IR spectrum and indicate the bond and wavenumber associated with each peak. Elucidate the structure of compound P and assign each peak in the 'H and 13C NMR spectra. (Hint: The compound consists of more than one functional group). а. b.

Suppose a student is preparing a set of standard solutions for use in a spectrophotometric study. If percent transmittance, %T, were measured in the standard solutions before the color had a chance to fully develop, the measured value would be compared with solutions that have allowed the color to fully develop.
