Construct a simulated HNMR spectru m, including proton integrations, for CH3CHCI2. Drag the appropriate Degrees of Unsaturation 2c 2 N-H -x C carbons H hydrog splitting patterns to the approximate chemical shift positions; place the integration values in the small bins N snitrogens X. trhaloger above the associated chemical shift. Splitting patterns and integrations may be used more than once, or not at all,...

Draw the expected H NMR spectrum for each molecule. Pay
attention to the chemical shift and splitting. Mark the integration
of each peak. Then assign each peak in the NMR to hydrogen atoms in
the structure.
