Chapter 16, Problem 16.46P
Interpretation Introduction

(a)

Interpretation: The given products is to be labeled as 1,2product and 1,4product.

Concept introduction: Diene is a hydrocarbon that contains two C=C double bonds in a compound. Conjugated diene consists of two double bonds that are separated by a single bond, whereas isolated diene also consists of two double bond but they are separated by two more carbon atoms.

Interpretation Introduction

(b)

Interpretation: The given products are to be labeled as kinetic and thermodynamic product.

Concept introduction: Diene is a hydrocarbon that contains two C=C double bonds in a compound. Conjugated diene consists of two double bonds that are separated by a single bond.

Interpretation Introduction

(c)

Interpretation: The reason as to why addition of HCl occurs at the indicated C=C (called an exocyclic double bond), rather than the other C=C (called an endocyclic double bond) is to be explained.

Concept introduction: The reaction of hydrogen halide with alkene results in the formation of alkyl halide. This type of reaction is an electrophilic addition of hydrogen halide.

Electrophilic addition reactions are those in which breaking of pi bond take place to form new sigma bond.

Addition of HCl to alkene X forms two alkyl halides Y and Z.a.Label Y and Z as a 1,2-addition product or a 1,4-addition product. b. Label Y and Z as the kinetic or thermodynamic product and explain why. c.Explain why addition of HCl occurs at the indicated C=C (called an exocyclic double bond), rather than the other C=C (called an endocyclic double bond).
What are the intermediates J, K and L? What regiochemistry and stereochemistry is involved in each step? Why is M the only stereoisomer formed?
Consider the following two-step reaction: a.How many bonds are broken and formed in Step [1]? Would you predict the ΔHo of Step [1] to be positive or negative? b.How many bonds are broken and formed in Step [2]? Would you predict the ΔHo of Step [2] to be positive or negative? c.Which step is rate-determining? d.Draw the structure for the transition state in both steps of the mechanism. e.If ΔHooverall is negative for this two-step reaction, draw an energy diagram illustrating all of the information in parts (a)–(d).
