Chapter 22, Problem 22.46P

Interpretation Introduction

(a)

Interpretation:

The product that would be formed when methyl methacrylate ( methyl $2\text{-}$ methyl propanoate) reacts with ${}^{-}\text{CN}$ and $\text{HCN}$ in $\text{MeOH}$ is to be predicted.

Concept introduction:

Methyl methacrylate is an ester of methanol and methacrylic acid. The methyl methacrylate has an alkene functional group and an ester functional group. These functional groups of methyl methacrylate can undergo nucleophilic conjugate addition reaction.

Interpretation Introduction

(b)

Interpretation:

The product that would be formed when methyl methacrylate ( methyl $2\text{-}$ methylpropenoate) reacts with ${\text{C}}_{\text{2}}{\text{H}}_{\text{5}}\text{SH}$ and $\text{NaOMe}$ catalyst in $\text{MeOH}$ is to be predicted.

Concept introduction:

Methyl methacrylate is an ester of methanol and methacrylic acid. The methyl methacrylate has an alkene functional group and an ester functional group. These functional groups of methyl methacrylate can undergo nucleophilic conjugate addition reaction.

Interpretation Introduction

(c)

Interpretation:

The product that would be formed when methyl methacrylate ( methyl $2\text{-}$ methylpropenoate) reacts with $\text{HBr}$ is to be predicted.

Concept introduction:

Methyl methacrylate is an ester of methanol and methacrylic acid. The methyl methacrylate has an alkene functional group and a ester functional group. These functional groups of methyl methacrylate can undergoes nucleophilic conjugate addition reaction.

Interpretation Introduction

(d)

Interpretation:

The product that would be formed when methyl methacrylate ( methyl $2\text{-}$ methylpropenoate) reacts with $\text{NaOH}$ is to be predicted.

Concept introduction:

Methyl methacrylate is an ester of methanol and methacrylic acid. The methyl methacrylate has an alkene functional group and an ester functional group.

Esters in the presence of base undergo saoponification reaction to from sodium salt of carboxylic acid and alcohol.
