PMT 4-nitrophenol can be converted into a range of useful organic products. 14 O2N OH 4-nitrophenol (a) 4-nitrophenol can react with three different reagents. Complete the table by:drawing the structures of the organic products formed, identifying the non-organic products formed. reagent organic product structure identity of non-organic product Na(s) Br2(aq) CH3COCl (l) [4]UCLES 2015 9701/43/O/N/15<br /> 15 (b) 4-nitrophenol can also be used in the synthesis of the dye Mordant Brown by the following route. In step 2 of this synthesis, 4-nitrophenol reacts with intermediate F made from amine E. Assume that the SO3Na+ group does not react. PMT E (C6H8N3SO3Na) step 1 OH NO2 OH NO2 step 2 H2N NH2 SO3Na+ Mordant Brown (i) Suggest structures for compounds E and F and draw them in the boxes above.
