Construct a simulated 1H NMR spectrum, including proton
integrations, for CH3CHCl2. 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.

Construct a simulated 1H NMR spectrum for 2-chloropropane by dragging and dropping the appropriate splitting patterns into the boxes on the chemical shift baseline, and by dragging integration values into the small box above each signal. Items may be used more than once. Peak heights do not represent integration. It has signals at 1.5 and about 3.8 ppm
