Practice Problem 6‐44 – Answer For each compound, indicate which group on the ring is the more strongly activating and then draw a structural formula of the major product formed by nitration of the compound. more strongly activating more strongly activating more strongly activating more strongly activating more strongly activating more strongly activating Practice Problem 6‐45 – Answer Show reagents and conditions to bring about the following conversions. Part (c) was deleted since we did not cover nucleophilic aromatic substitution reactions… Practice Problem 6‐46 – Answer Propose a synthesis for each compound from benzene. Practice Problem 6‐47 – Answer Starting with benzene, toluene, or phenol as the only sources of aromatic rings, show how to synthesize the following. Assume in all syntheses that mixtures of ortho‐para products can be separated into the desired isomer. (a) 1‐Bromo‐3‐nitrobenzene (b) 1‐Bromo‐4‐nitrobenzene (c) 2,4,6‐Trinitrotoluene (d) m‐Chlorobenzoic acid (e) p‐Chlorobenzoic acid (f) p‐Dichlorobenzene (g) m‐Nitrobenzenesulfonic acid (h) 3,5‐Dichloro‐2‐methoxybenzoic acid Practice Problem 6‐48 – Answer The following compound used in perfumery has a violet‐like scent. Propose a synthesis of this compound from benzene.
