Concept explainers
Name the following
(a) CH3CH2CH2NH2
(b) (CH3)3N
(c) (CH3)(C2H5)NH
(d) C6H13NH2
(a)
Interpretation: The name of the following amine has to be written.
Concept introduction:
Amines are the derivatives of ammonia
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.
Answer to Problem 48PS
