Determine the product formed when each compound is treated with Br2 and FeBr3. Drag the atom labels to their appropriate positions. CN Atom labels H H Br Br2 A. FeBr Br H OH OH Br Br. Br2 FeBr3 H H Br Br H Br2 FeBr H1 H Reset T Rank the compounds in each group in order of decreasing reactivity in electrophilic aromatic substitution. CI Decreasing reactivity Rank the compounds in each group in order of decreasing reactivity in electrophilic aromatic substitution. NH2 ON HN ON Decreasing reactivity Classify each substituent as ortho, para activators; ortho, para deactivators; or meta deactivators. meta deactivators ortho, para deactivators ortho, para activators CHO COOH CI Br OCH OH SoH CN NH2 C(CHsa NO2 OCH CHO NO2 CN OH COOH Br C(CHsh NH2 Reset Rank the compounds in each group in order of decreasing reactivity in electrophilic aromatic substitution. NH2 NH2 NH2 NH2 Decreasing reactivity Rank the compounds in each group in order of decreasing reactivity in electrophilic aromatic substitution. ON OH HO ON Decreasing reactivity Select the best order of reagents to complete each of the following multi-step syntheses with the highest yield of the desired product Assume all subsequent reactions will proceed regardless of the presence of deactivating groups. HNO3 H2SO4 Cl2, AICI Cl2, FeCl CH3CI, AICI3 Cl2 NH2NH2 SO3. H2SO Zn(Hg), HC Sn, HC Cl2, hv HOT HNO3 H2SO Cl2, FeCl3 ON A. HNO3 H2SO4 Cl, FeCl ON B. CI Select the keyword or phrase that will best complete each sentence. Key terms: Toluene reacts faster than benzene in all substitution reactions. Thus, its electron- donating CHs group activates the benzene ring to electrophilic attack acid activates A resonance effect is electron donating when resonance structures place a negative charge on carbons of the benzene ring base Inductive effects stem from the electronegativity of the atoms in the substituent and the polarizability of the substituent groups. deactivates donating In a Friedel-Crafts alkylation, benzene is treated with an alkyl halide and a Lewis acid (AICIS) to form an alkyl benzene. donation electronegativity When a neutral O or N atom is bonded directly to a benzene ring, the resonance effect dominates and the net effect is electron donation inductive polarizability Nitrobenzene réacts more slowly than benzene in all substitution reactions. Thus, its electron-withdrawing NO2 group deactivates the benzene ring. poor resonance A resonance effect is electron withdrawing wherr'resonance structures place positive charge on carbons of the benzene ring rich When a halogen is bonded to a benzene ring, the inductive effect dominates and the net effect is electron withdrawal withdrawal withdrawing An alkyl group is an electron-donating group and an alkyl benzene is more electron rich than benzene. Rank the compounds in each group in order of decreasing reactivity in electrophilic aromatic substitution. Decreasing reactivity Select the best order of reagents to complete each of the following multi-step syntheses with the highest yield of the desired product Assume all subsequent reactions will proceed regardless of the presence of deactivating groups.
