5) Provide a structure consistent with all of the data for the following compounds. Unless otherwise stated, the IR data is not all inclusive, i.e. you may propose a structure which would include peaks not specifically noted but your structure must account for the peaks which are listed or which are excluded. a) Compound Q (C6H100) decolorizes Br2/CC14. IR peaks at 3500 cm- and 1640 cm"! NO absorption between 1700 and 1800 cm? b) Compound K (C6H100) does not decolorize...
