Chapter 15.5, Problem 15.14P

Interpretation Introduction

(a)

Interpretation:

The chirality center in the molecule of propranolol should be labeled.

Concept Introduction:

Organic compounds are the compounds that are mainly composed of C and H atoms. The branch of chemistry that deals with the preparation, reactions and properties of organic compounds called organic chemistry. The molecular formula of an organic compound represents the number of bonded atoms with their atomic symbols. The structural formula represents all the bonded atoms with chemical bonds and the arrangement of atoms in the molecule. The compounds with same molecular formula and different structural formula are called isomers. Isomers can be classified as constitutional isomers and stereoisomers.

Constitutional isomers can be defined as the pair of molecules with same molecular formula but different structural formula. Stereoisomers have same molecular and structural formula, but they have different arrangements of atoms in the three-dimensional space.

Interpretation Introduction

(b)

Interpretation:

The enantiomers of Propranolol molecule should be drawn.

Optical isomers are type of stereoisomers which have same molecular and structural formula butdifferent arrangement of atoms in the three-dimensional space. The essential condition for a molecule to be optical isomer is the presence of chiral carbon atom.

Interpretation Introduction

(c)

Interpretation:

The enantiomer of Propranolol molecule that can show binding with chiral receptor should be drawn.
