Chapter 4, Problem 4.32EP

(a)

Interpretation Introduction

Interpretation:

The given ketone has to be named using IUPAC nomenclature.

Concept Introduction:

For naming a ketone in IUPAC nomenclature, the suffix “-one” is added to the parent alkane name.

IUPAC rules for naming a ketone:

• • The longest parent carbon chain is identified that includes the carbonyl group.
• • The parent chain name is changed by replacing the suffix “-e” with “-one”.
• • Numbering is done in a way that the carbonyl group gets the least numbering.  The position of the carbonyl group is indicated in the name.
• • The identity and location of substituents if any has to be determined and this information has to be added in front of the IUPAC name.
• • Cyclic ketones are named by adding the suffix “-one” to the name of the carbon ring.  The substituents are numbered so that it gets the least numbering starting from the carbonyl group that is given the number 1.
