Q:Repeat Problem 4.31 for the chlorination of acetophenone, and explain why the product is m-chloroacetophenone. Problem 4.31 Draw all possibleQ:When benzene is treated with propene and sulfuric acid (see structures of reactants below), two different monoalkylation products are possible. DrawQ:In aromatic chlorinations, we use FeCl3 with Cl2 as the reagents, and for aromatic brominations, we use FeBr3 with Br2. Suggest a reason as to whyQ:When benzene is treated with excess D2SO4 at room temperature, the hydrogens on the benzene ring are gradually replaced by deuterium. Write aQ:Draw a molecular orbital picture for the resonance hybrid benzenonium ion shown in eq. 4.16, and describe the hybridization of each ring carbon atom.Q:Predict whether the following substituents on the benzene ring are likely to be ortho, para directing or meta directing and whether they are likelyQ:For each of the monosubstituted benzenes shown below,(1) Indicate whether the substituent is ortho, para directing or meta directing.(2) Draw theQ:When toluene (C6H5CH3) is treated with 2-methyl-2-butene and sulfuric acid, two products are observed. What are the structures of the two products?Q:How does the resonance model for benzene explain the fact that there are only three isomers of dibromobenzene?Q:Which compound is more reactive toward electrophilic substitution (for example, nitration)?
