Construct a simulated 'H NMR spectrum for 1,1-dibromoethane. Drag and drop the appropriate splitting patterns into the boxes on the chemical shift baseline, and add integration values above each signal. Splitting patterns and integrations may be used more than once. Peak heights do not represent integration values. Br Br 1H 3H O ppm 4 3 Answer Bank
