Chapter 15, Problem 15.84AP

Interpretation Introduction

(a)

Interpretation:

The curved arrow mechanism for the given transformation is to be stated.

Concept introduction:

Alcohols, when treated with an alkyl halide, undergo nucleophilic substitution reactions. Nucleophilic substitutions are of two types, ${\text{S}}_{\text{N}}1$ and ${\text{S}}_{\text{N}}2$. The products obtained from both the mechanisms are different.

Interpretation Introduction

(b)

Interpretation:

The mechanism for the given transformation is to be stated.

Concept introduction:

When an alkene reacts with water in the acidic medium, the reaction follows Markovnikov rule which states that the negative part of the reagent attacks the carbon with the least number of hydrogen atoms attached to it.

Interpretation Introduction

(c)

Interpretation:

The mechanism for the given transformation is to be stated.

Concept introduction:

Diels Alder reaction is the reaction between a substituted alkene which is known as dienophile and conjugated alkene known as diene. There is the formation of a new $\sigma$ bond and loss of $\text{π}$ bond takes place.

Interpretation Introduction

(d)

Interpretation:

The mechanism for the transformation is to be stated. The compound, X is to be identified. The reason for the fact that the equilibrium for the reaction of X strongly favors the product is to be stated.
