Chapter 25.5, Problem 25.15P
Interpretation Introduction

(a)

Interpretation:

Between morphine and heroin, which compound is more polar should be determined.

Concept Introduction:

The polar compound is those compounds, which carry a small charge due to the attraction of electron towards the electronegative region within the compound. The polar compound may carry a slight negative or slight positive charge.

Interpretation Introduction

(b)

Interpretation:

Between morphine and heroin, which compound can cross the blood-brain barrier more easily should be determined.

Concept Introduction:

The blood-brain barrier is a highly selective membrane, which allows a few molecules to pass through it. It separates the blood and the extracellular fluid from the brain in CNS (central nervous system).

Interpretation Introduction

(c)

Interpretation:

Between morphine and heroin, which compound is a better pain reliever should be determined.

Concept Introduction:

The blood-brain barrier is a highly selective membrane, which allows a few molecules to pass through it. It separates the blood and the extracellular fluid from the brain in CNS (central nervous system). For a compound to be better in terms of pain-relieving properties, it should be easily in the brain cells.
