Concept explainers
(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.
(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).
(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.
