a.
Answer to Problem 41A
Explanation of Solution
In Butan-1-amine the longest carbon chain is made up of four carbons and the amine is attached to the first carbon. The substituent is named first and then the longest carbon chain and then the suffix of the amine group. Therefore, in this case, the name is Butan-1-amine.
b.
Interpretation: To give the IUPAC names for the amines given.
Concept Introduction: The nomenclature is generally based on the parent alkane chain which is the longest chain containing the amine group. The suffix for amines will be ‘amine.’ Number the alky chain in such a way that amine will get the lowest number and then name the substituent if any along with the number of the carbon to which the substituent is attached. Finally, write the IUPAC name of the amine with the suffix ‘amine’
b.
Answer to Problem 41A
Explanation of Solution
In Ethan-1-amine the longest carbon chain is made up of two carbons and the amine is attached to the first carbon. The substituent is named first and then the longest carbon chain and then the suffix of the amine group. Therefore, in this case, the name is Ethan-1-amine.
