Question 9 If reaction Pathway A is carried out at high temperatures, a trisubstituted product forms. Which of the following compounds is the possible trisubstituted derivative? O2N- -Br O2N- -Br -Br Br A. O,N B Br NO2 NO2 O,N- -Br ON- -NO2 Question 10 Which of the following is a correct statement regarding electrophilic aromatic substitution? A. The carbocation intermediate will lose a proton to regain aromaticity, usually from a position other than the site of electrophilic attack. B. Formation of the carbocation intermediate has a high activation barrier due to loss of aromaticity. C. The carbocation intermediate has several resonance structures and is negatively charged. D. Reformation of the aromatic ring has a low activation barrier and therefore occurs slowly. E. Many suitable electrophiles are unreactive and can be stored for long periods of time prior to use.
