Q6. Complete Table 6. i) Copy and paste (insert) the correct alternative of the structures below into the table, ii) insert expected number of different ¹H and 1³C environments expected for these compounds (Table 6: columns 2 and 3 respectively) and correctly label the ¹H and ¹³C NMR spectra below in boxes provided .CI CI Table 6: Assigning NMR spectra for aromatic Structures of disubstituted No. of expected ¹H NMR peak/s benzene compounds 1,2-dichorobenzene 1,3-dichorobenzene .CI 1,4-dichorobenzene CI compounds No. of expected ¹³℃ NMR peak/s

Assigning Spectra: The peak at 0.9 ppm is a doublet, integrating to 6. Assign this peak to a fragment (Which statement is most correct?) * 20 10 ppm R2-CH-CH2-C(=0)-OR. Based on shift it could be a CH2 near carbonyl, with one neighboring proton. R2-CH-CH3. Could be a standard methyl, with one neighboring proton. O R-CH2-CH3. Could be a standard R-CH3, with 2 neighboring protons. RO-CH(R)-CH3. Could be standard methyl, with beta substituent, and one neighboring proton.

Consider the product below a) Would this product show a signal in a UV-Vis spectrum? Why? b) Would this molecule have a non-zero alpha-value in polarimetry? Why? c) What stretches would be expected in an IR spectrum of this molecule? d) Predict the 1H NMR spectrum for this molecule. For H1 to H6 e) Predict the 13C NMR spectrum and DEPT spectra for Carbon A- Carbon G. Use (+) for positive signals, (-) for negative signals, and (X) for no signal in the DEPT NMR spectra. f) If a base such as NaOH was used, it would be harder to determine the major product before running the reaction. Once the reaction was run, how would you determine the product favored using spectroscopy?
