Chapter 10, Problem 10.41P

(a)

Interpretation Introduction

Interpretation:

Possible number of stereoisomers for the given compound has to be detected.

Concept Introduction:

Stereoisomers: The molecule that have same molecular formula and sequence of bonded atoms, but different in the three-dimensional orientation of their in space.

Chiral: Chiral molecules contain at least one carbon atom with four non-identical substitutions (or) groups. This type of molecule is called a chiral center.

Diastereomers: This type of stereoisomers that ae not mirror images of one another and non-superimposable on one another. Molecule with two or more stereocenters it can be diastereomers.

Meso isomers: The molecule with multiple stereocenters that is superimposable on tit mirror images. Meso compounds are achiral that are multiple chiral center.

(b)

Interpretation Introduction

Interpretation:

The stereoisomers of given compound that can be formed from oxidation of (S)-4-methylcyclohexene with Osmium tetroxide has to be predicted.

Concept Introduction:

Stereoisomers: The molecule that have same molecular formula and sequence of bonded atoms, but different in the three-dimensional orientation of their in space.

An alkene undergoes an oxidation reaction with Osmium tetra oxide and followed by hydrolysis to give a cis 1, 2 diol for example,

(c)

Interpretation Introduction

Interpretation:

Whether product formed in part (b) is either optically active or not has to be predicted.

Concept Introduction:

Stereoisomers: The molecule that have same molecular formula and sequence of bonded atoms, but different in the three-dimensional orientation of their in space.

Chirality: The presence of four different atoms (or groups) at carbon is known as asymmetric carbon and is known as chiral center of the compound. Chiral compounds are optically active.
