Predict the H NMR Spectrum of product. 1. Identify unique H groups and label Hª, H, H²..... of each signal 2. Estimate chemical shift -range 3. Predict splitting pattern of each signal

Construct a simulated 'H NMR spectrum, including proton integrations, for CH, CHCI, . Drag the appropriate splitting patterns to the approximate chemical shift positions; place the integration values in the small bins above the associated chemical shift. Splitting patterns and integrations may be used more than once, or not at all, as needed. Likewise, some bins might remain blank. Note that peak heights are arbitrary and do not indicate proton integrations. 7 6. 5 4 3 2 1 O ppm Answer Bank 2H 3H 1H 4H

4.Predict the NMR spectra for each of these two compounds by listing, in the NMR tables below, the chemical shift, the splitting, and the number of hydrogens associated with each predicted peak. Sort the peaks from largest chemical shift to lowest.  5. Using the peak information listed in the tables for both structures, assign each peak to that portion of the structure that produces the peak in the NMR spectrum.

Signature: Q1. For each of the following molecules, determine how many signals you would expect to see in an ¹H-NMR spectrum of the molecule. Additionally, label each of the hydrogen atoms (A, B, C, ...) such that those in the same chemical environment are given the same designation and determine the expected splitting for all protons (s, d, t, q, m etc.). a. b. Q2. How many 13C signals would you expect for the following compounds? a. LOH b. CI H
