Interpretation:
The reason of easy conversion of pseudoephedrine to methamphetamine but difficult to convert phenylephrine to methamphetamine needs to be explained.
Concept Introduction:
Organic compounds are the compounds which are mainly composed C and H atoms. The branch of chemistry that deals with preparation, reactions, and properties of organic compounds. The molecular formula of organic compound represents the number of bonded atoms with their atomic symbols.
