During the mechanism of the following reaction to produce the major product (only), what is the most proper statement? HNO3 H2SO4 a. The electrophilic species "OSO3H (sulfonate ion) adds to the benzene in the para position. b. The electrophilic species +H2NO3 (protonated nitric acid ion) adds to the benzene in the para position. c. The electrophilic species SO3 (sulfur trioxide) adds to the benzene in the para position. d. The electrophilic species +NO2 (nitro ion) adds to the benzene in the para position. e. The electrophilic species "OSO3H (sulfonate ion) adds to the benzene in the ortho position. f. The electrophilic species +H2NO3 (protonated nitric acid ion) adds to the benzene in the ortho position. g. The electrophilic species SO3 (sulfur trioxide) adds to the benzene in the ortho position. h. The electrophilic species +NO2 (nitro ion) adds to the benzene in the ortho position. What is the best response for the following statement? "When chloroethane is added to a flask containing aniline and an AlCl3 catalyst, o-ethylaniline and p-ethylaniline are formed." a. True, the amine group of aniline is an activator and an ortho/para director, so the Freidel- Crafts alkylation leads to these products. b. False, although the amine group of aniline is an activator and an ortho/para director, the amine group will complex with the catalyst and the Freidel-Crafts alkylation will not take place. c. True, although the amine group of aniline is a deactivator, it will act as an ortho/para director in the Friedel-Crafts reaction because the catalyst will be used up. d. False, the amine group of aniline is a deactivator and a meta director, so the Freidel-Crafts alkylation leads to different products
