In the tables below. He in the expected integration, splitting pattem and approximate coupling constant for...
Shown below is the peak list of chemical shifts, multiplicities, numbers of protons (from integration), and coupling constants for the 1H NMR spectrum in Question 4. a) Draw the chemical structure of trans-4-nitrochalcone. Circle the proton or protons that you would attempt to identify in the 1H NMR spectrum as evidence that the expected trans-isomer was formed (rather than the cis-isomer). b) Identify the peak or peaks in the peak list that correspond(s) to the proton or protons circled in...
What is the splitting and integration for the protons indicated below? triplet, 2H multiplet (5), 1H singlet, 1H doublet, 1H triplet, 1H NH2 OOO The integration on a 'H NMR spectra containing three peaks is as follows for a molecule with the molecular formula C6H12O; A = 18, B = 12, and C = 6.0. How many hydrogens does peak B represent? OB = 12 B = 2 B = 6 B = 6.0 B=4 Draw the structure for 2,4Z-2-bromo-4-ethyl-2,4-hexandiene....
