Chapter 16, Problem 16.53P

(a)

Interpretation Introduction

Interpretation:

Two sets of reagents that might be used to prepare the given Z alkene has to be proposed.

Concept Introduction:

Wittig reaction:

Formation of an alkene by the reaction of carbonyl compounds with phosphorus ylide is known as Wittig reaction.

(b)

Interpretation Introduction

Interpretation:

The conversion method of Z alkene into disparlure has to be given.

Concept Introduction:

Epoxidation reaction:

Alkenes reacts with peracids and forms epoxide.

(c)

Interpretation Introduction

Interpretation:

The number of possible stereoisomers for disparlure has to be given.

Concept Introduction:

Stereoisomers and chiral:

Isomers differing only in their spatial arrangement of atoms are called as stereoisomers.

The geometric property of a molecule that cannot be superimposed on its mirror image is known as chirality.  Chiral carbon is the one which is attached with four different groups or atoms.
