Select the statements that explain why over-acylation of benzene does not occur in the aluminum trichloride catalyzed Friedel-Crafts EAS reaction of benzene with 2-methylpropanoyl chloride and that explain why no products arising from rearrangement of acylium cation are formed. AICI None All 1.) Over-acylation does not occur because proton loss and rearomatization (the second step) of the EAS reaction is fast and occurs before a second acylation can happen. 2.) Over-acylation does not occur because aluminum trichloride is not a strong enough catalyst. 3.) Over-acylation does not occur because the activation energy for the first step of the acylation of an acylated-benzene is higher than for the first step of the acylation of benzene. 4.) Over-acylation does not occur because the ratio of acyl chloride to benzene can be optimized. 5.) Rearrangement products aren't formed, because the first step of the acylation reaction happens before the acylium cation has a chance to rearrange. 6.) Rearrangement products aren't formed, since the acylium cation is the most stable cation. 7.) Rearrangement products aren't formed, because the acylium cation has two resonance forms. 8.) Rearragement products aren't formed, because benzene is used as solvent a.) Statements 1.) and 5.) d.) Statements 4.) and 6.) b.) Statements 2.) and 7.) e.) Statements 4.) and 8.) c.) Statements 3.) and 5.) f.) Statements 3.) and 6.)
