13 The compounds C2H5COOCH3 and CH3COOC2H5 are most easily differentiated by the infrared spectra outside the fingerprint region. fragmentation patterns in their mass spectra. C splitting patterns in their high resolution nmr spectra. D numbers of peaks in their low resolution nmr spectra. 14 The infrared spectrum of an organic compound with molecular formula C8H8O2 has a strong peak in the range 17001680 cm1 and a broad peak above 3300 cm1. (Total for Question 13 = 1 mark) The compound could be A H B C C C 3CC6H4COOH 6H5CH2COOH 6H5COOCH3 D HOC 6H4COCH3 15 An organic compound is very soluble in water forming an alkaline solution that reacts with copper(II) ions to give a coloured product. (Total for Question 14 = 1 mark) The compound is most likely to be A C B C C C D C 4H9NH2 4H9CN 6H5NH2 6H5NO2 16 The polymer poly(ethenol), which has the formula [CH2CH(OH)]n is used to make capsules for liquid detergents because (Total for Question 15 = 1 mark) it is inert. it is water-soluble. C London forces between its molecules are very strong. it neutralises acids that could harm fabrics.
