Chapter 18, Problem 18.41P
You have learned two ways to make an alkyl benzene: Friedel–Crafts alky lation, and Friedel–Crafts acylation followed by reduction. Although some alkyl benzenes can be prepared by both methods, it is often true that only one method can be used to prepare a given alkyl benzene. Which method(s) can be used to prepare each of the following compounds from benzene? Show the steps that would be used.

Which method(s) can be used to prepare attached compound from benzene? Show the steps that would be used.
Which of the following statements is correct?
A) The haloform reaction proceeds under very difficult conditions and the yield is very low.
B) The haloform reaction is used only for the identification of compounds containing secondary alcohol groups.
C) Methyl ketones or alcohols are oxidized with halogens in acidic solutions to give carboxylic acids and the appropriate haloform product.
D) Enolate anions react rapidly with halogens to give alpha-halocarbonyl compounds.
Enamines can serve as enolate surrogates in reactions at the a-carbon. In the reaction sequence, the structures of the enamine
addition product – the initial zwitterion and its neutral tautomer – are shown. Draw the structures of the two reactants forming
these intermediates, and draw the structure of the final product, obtained via hydrolysis of the neutral intermediate.
