Interpretation:
The condensed structural formula for the ammonium salt (procaine hydrochloride) is to be drawn. Secondly it has to be described why procaine hydrochloride is used rather than procaine.
Concept Introduction:
Procaine is a local anesthetic drug of the amino ester group. It is used primarily to reduce the pain of intramuscular injection of penicillin, and it is also used in dentistry. Procaine is used therapeutically due to its sympatholytic and mood-enhancing effects.
In primary amines, the N atom has one alkyl group (R) and two hydrogen atoms; with a general structure RNH2.
In secondary amines, the N atom has two alkyl groups (R) and one hydrogen atom; with a general structure R2NH.
In tertiary amines, the N atom has three alkyl groups (R) and no hydrogen atoms; with a general structure R3NH.
Amines react with an acid (H+ ion) to give the corresponding conjugate acid.
The condensed formula of a molecule is the formula where the symbols of atoms are listed in order as they appear in the molecule's structure with bond dashes omitted or limited.
To determine: The condensed structural formula for the ammonium salt (procaine hydrochloride) is to be drawn. Secondly it has to be described why procaine hydrochloride is used rather than procaine.
