Chapter 18, Problem 41P

Interpretation Introduction

Interpretation:

The structures for the four amines of molecular formula C₃H₉N should be drawn. The systematic name for each amine should be given.

Concept Introduction:

There are three types of amines as primary, secondary and tertiary. Primary amine has one C-N bond. Secondary amine has two C-N bonds. Tertiary amine has three C-N bonds. In nomenclature of primary amine, the longest carbon chain bonded to nitrogen is determined and the −e ending of the parent alkane is replaced by the suffix −amine. Usual rules are used in numbering and naming substituents. In nomenclature of secondary or tertiary amines identical alky groups are named by using a prefix such as di- or tri-. If there are different kinds of alkyl groups they are named as N-substituted primary amines.
