Chapter 10, Problem 71P

Explain why pentane-2,4-dione forms two alkylation products (A and B) when the number ofequivalents of base is increased from one to two.

Rank the following esters in order of decreasing reactivity in the first slow step of a nucleophilic acyl substitution reaction (formation of the tetrahedral intermediate):Rank the same esters in order of decreasing reactivity in the second slow step of a nucleophilic acyl substitution reaction (collapse of the tetrahedral intermediate).

Provide a mechanism for the following reaction. Show each step in your mechanism and use curved arrows to show the movement of electron pairs. Hint: the first step is a proton transfer; second step, nucleophilic attack

Draw the products formed when each compound is treated with HNO3 and H2SO4.State whether the reaction occurs faster or slower than a similar reaction with benzene.

Draw the most stable product formed in each of the reactions shown. Reaction (a) 2 NaOEt, EtOH A Draw the product of reaction (a).

Classify each of the following species as a nucleophile or an electrophile:

Acetal product formation requires an acid catalyst in the second step, but NOT in the first step. True or False?

Which compound can act as a nucleophile

Draw out a complete arrow-pushing mechanism for the following reaction. This reaction is explicitly done with heat. O NaOH, H₂O heat
