Interpretation Introduction

Interpretation:

IUPAC name of the given compound has to be chosen from the given options.

Concept Introduction:

IUPAC nomenclature for amine:  There are about five rules to be followed in giving IUPAC name for an amine.

• Longest carbon chain has to be identified that is attached to nitrogen atom.
• Suffix “-e” in name of the parent chain alkane is replaced by “-amine”.
• Numbering of the carbon chain is done from the end that is near the nitrogen atom.
• Point of attachment of the nitrogen atom in the carbon chain is indicated by a number before the parent chain name.
• In case if substituents are present, then the identity and location of substituents are appended to the front in the parent chain name.

If the compound contains two amine groups, then the suffix “-e” is replaced by diamine.  Tertiary and secondary amines are named as N-substituted primary amines.

Common name for amine is given in a single word.  Primary amine is named as alkylamine.  Secondary amine is named as alkylalkylamine.  Tertiary amine is named as alkylalkylalkylamine.
