1. For the following molecules, find the number of unique proton signals that would be observed in ¹H NMR. Label the equivalent protons and give the multiplicity and integration for each. See the example for methyl ethyl ketone. Please note that singlet or multiplicity 1 are both acceptable answers. Example: H3C H3C. H₂ H3C. CH3 H3C C -CH₂ CH3 H3C) A CH₂Cl2 OH -Br CH3 H₂ CH3 CH3 с H₂ B CH3 с 2. The following set of molecules each show a singlet. The chemical shifts (ppm) are 0.232, 3.052, 5.297 and 7.256. Match the shift to each molecule below. A: Singlet (Multiplicity 1) Integration 3 B: Quartet (Multiplicity 4) Integration 2 C: Triplet (Multiplicity 3) Integration 3 CHC13 CH,C1 CH4
