Chapter 2, Problem 46P

(a)

Interpretation Introduction

Interpretation: The structure of 4-Chloro-5-methylhexane corresponding to IUPAC name should be drawn and correct IUPAC name must be indicated.

Concept introduction: As per IUPAC recommendations longest chain found in a continuous manner in a branched molecule is chosen as parent chain.

The IUPAC name begins with prefix to designate the number of C atoms in the longest chosen parent alkane followed by the suffix −ane. The positions of side chains or substituents are indicated by lowest numeral places before prefix.

Names of branches that occur commonly as side chains are listed below:
