Chapter 13, Problem 13.40QP

(a)

Interpretation Introduction

Interpretation:

The IUPAC name of the aldehyde has to be provided.

Concept Introduction:

IUPAC Nomenclature for naming aldehydes:

• The parent compound; that is the longest continuous carbon chain containing the carbonyl group has to be determined.
• Replace the final –e of the parent alkane with –al.
• The chain beginning with the carbonyl carbon is named as carbon $\text{-1}\text{.}$
• All the substituents are named and numbered.
• No number is used for the position of carbonyl group because it is always at the end of the parent chain.  Therefore it must be carbon $\text{-1}\text{.}$

(b)

Interpretation Introduction

Interpretation:

The IUPAC name of the ketone has to be provided.

Concept Introduction:

IUPAC nomenclature of naming ketones:

• The parent compound that is the longest carbon chain containing the carbonyl group has to be determined.
• Replace the –e ending of the parent alkane with –one suffix of the ketone family.
• The carbon atom has to be numbered.  The carbonyl carbon takes the lowest possible number.
