1. NMR analysis: Draw the full structure of diphenylmethanol. Show all bonds to the hydrogens. Label the different sets of hydrogens (i.e. Hạ. Hp, H1, H2, etc) based on which ones are equivalent and which ones are not. Assign each set of hydrogens with a specific signal on the spectrum. Create a table that summarizes: the chemical shift, integration, multiplicity, proton assignment, and justification of each signal.

Construct a simulated proton-decoupled ¹³C NMR spectrum for tert-butylamine. Drag the resonance signal to the appropriate chemical shift positions. Then label the box above each signal with the expected splitting if there were no proton decoupling. The splitting abbreviations are s = singlet, d = doublet, t = triplet and q = quartet.

Based on the H-NMR, which compound is the sample is? Please provide the integration, multiplicity and also assign the chemical shift to each H in the compound.

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
