Experiment 3 Liquid-Liquid Extraction Discussion The success of extracting each compound out of the solution can be seen in the IR graphs for each substance. For ethyl 4-aminobenzoate‚ the N-H‚ C=O and C-O are distinguishable in their proper wavenumber positions. The amino N-H stretch was found between 3224 cm-1 and 3423 cm-1. The C=O was found at 1681 cm-1 and the C-O was at 1280 cm-1. The IR for benzoic acid also displays its significant bonds‚ O-H and C=O. The O-H was between 2566 and
