Chapter A, Problem A.46P

Interpretation Introduction

(a)

Interpretation:

The IUPAC name of the given molecule is to be written.

Concept introduction:

The root name of the molecule is the name of the alkane, which depends on the longest continuous chain of carbon atoms or the ring structure. The name of the substituent attached to the parent ring is written as a prefix to the left side of the root. The parent ring is numbered such that the carbon atom to which the substituent is attached gets the lowest possible number. This number is written on the left side of the substituent and separated by a hyphen. If more than one substituent is present, then the numbering is determined by the alphabetical order of substituents.
