Chapter 10.9E, Problem 10.19P

(a)

Interpretation Introduction

To determine: The synthesis of given alcohol $2$-phenylethanol by adding Grignard reagent to ethylene oxide.

Interpretation: The synthesis of given alcohol $2$-phenylethanol by adding Grignard reagent to ethylene oxide is to be shown.

Concept introduction: Epoxide is three member ring which has formula ${\text{CH}}_{\text{2}}{\text{OCH}}_{\text{2}}$. They are reactive ethers due to ring strain present in them. They are also known as ethylene oxide.

They react with Grignard reagent to give primary alcohols with two additional carbon atoms after the protonation.

(b)

Interpretation Introduction

To determine: The synthesis of given alcohol $4$-methylpentan-$1$-ol by adding Grignard reagent to ethylene oxide.

Interpretation: The synthesis of given alcohol $4$-methylpentan-$1$-ol by adding Grignard reagent to ethylene oxide is to be shown.

Concept introduction: Epoxide is three member ring which has formula ${\text{CH}}_{\text{2}}{\text{OCH}}_{\text{2}}$. They are reactive ethers due to ring strain present in them. They are also known as ethylene oxide.
