Chapter A, Problem A.25P

Interpretation Introduction

(a)

Interpretation:

IUPAC name for the molecule is to be written.

Concept introduction:

In the IUPAC nomenclature, the longest continuous carbon chain is considered as the parent chain. The name of this corresponding parent chain will be the root of the molecule’s name. Identify the substituents and add the name of the substituent as a prefix to the left of the root. In case of two or more different substituents, the alphabetical order is considered. Number each carbon atom of the chain sequentially, beginning with $\text{C1}$ at one end of the chain, so that the carbon atom to which the substituent is bonded receives the lowest possible number. The number assigned to the carbon that is bonded to the substituent is called the locator number or locant. The locator number is written to the left of the substituent name and a hyphen is added to separate the locator number from the rest of the name.

Number each carbon atom of the chain sequentially, beginning with $\text{C1}$ at one end of the chain, so that the carbon atom to which the substituent is bonded receives the lowest possible number. If each choice for $\text{C1}$ results in a tie for the locator number of the first substituent, then $\text{C1}$ is chosen so that the second substituent encountered has the lowest locator number. The number assigned to the carbon that is bonded to the substituent is called the locator number or locant. The locator number is written to the left of the substituent name and a hyphen is added to separate the locator number from the rest of the name.
