For the molecule below (all protons have been shown and labeled)... Fill in the table with the relevant values. For the "splitting" row, use the following abbreviations for singlet, doublet, triplet, quartet, pentet, hextet: s, d, t, q, p, h. Sketch the expected 'H NMR spectrum for the molecule in the area below. Label your peaks with the corresponding letters (A, B, C, etc...). HH 5 HHH3C CH3 OH HH E 4 Proton 8 Integral Splitting 3 A B 2 C 1 D E

Based on the spectra provided, draw the structure. Label each unique carbon and hydrogen with the letters A, B, C… for use in assigning NMR peaks. fill in the data table assigning peaks in each spectrum. You should assign: • All 1H NMR peaks • Significant IR peaks above 1600 cm Example of what the table should include (imagine the structure of ethanol is drawn with the CH3 hydrogens labeled as A, the CH2 hydrogens labeled as B, and the OH hydrogen labeled as C) :  hydrogen proton chemical shift  integration splitting pattern couples to.. A 1.2 3 triplet B B 3.7 2 quartet A C 2.6 1 singlet -

7. Determine the structure of the compounds below from their spectroscopy data. Sketch the 'H-NMR spectra of the following a and b compounds. Assign peaks to the structures. a) C3H10 1.2 8 (3H, triplet) 2.6 8 (2H, quartet) 7.1 8 (5H, broad singlet) b) C4H7BrO 2.11 8 (3H, singlet) 3.52 8 (2H, triplet) 4.40 8 (2H, triplet) Cs Scanned with CamScanner

Which of these choices best describes the interpretation of the following peak that may be recorded in a 'H NMR spectrum? 3.0 8 (1H, t). The underlined hydrogen atom is intended to be the one producing the peak that we are interpreting. Ar-CHCO2H Ar-CHCHX2 Ar-CHCH,X Ar-CHCH3 None of these interpretations describes this peak.

III) Can 1H NMR spectroscopy be used to differentiate between the two compounds? Briefly explain why or why not. Predict the 1H NMR spectrum for each compound (include integration, multiplicity, and approximate chemical shift). For each set, be sure that you put them in a data table format!

please answer with structure and name of chemical compound!

Match the four structures with the four IR spectra (by putting a proper letter in the box to the right of each spectrum). Use specific IR absorptions for various functional groups to identify the structures. Circle the important peaks in each spectrum that helped you identify the functional group(s) and label the functional group beside it.

Which of these choices best describes the interpretation of a 'H NMR spectral peak that was recorded as 0.95 8 (3H, t)? The underlined hydrogen atom is intended to be the one producing the peak that we are interpreting. CH-CH2 CH2-CH2 CH3-CH2 CH2-CH2-CH2 CH3-CH2-CH3 None of these interpretations describes this peak.

Please answer question 5,7 and 9 step-by-step thank you.
