Interpretation:
The structure of hydrogen chloride salt of promazine has to be drawn.
Concept Introduction:
Promazine: It is a type of drug used as an antipsychotic tranquilizer. It is consumed as hydrogen chloride salt of promazine.
Depending on the number of carbon side chain of the nitrogen, different types of amines can form.
Primary amines can be named in the IUPAC system in several ways,
For simple amines the suffix – amine is added to the name of the alkyl substituent.
The suffix-amine can be used in place of the final –e in the name of the parent compound.
For a secondary amine an N prefixes the compound giving the shorter carbon chain and its chain prefix name.
For a tertiary amine an N, N prefixes the compound giving the two shorter carbon chains and their side chain prefix names.
In a quaternary ammonium ion a nitrogen atom with four attached groups is positively charged. And their compounds are known as quaternary ammonium salt.
