Chapter 11, Problem 11D.18E

(a)

Interpretation Introduction

Interpretation:

The systematic name for ${\text{CH}}_{\text{3}}\text{CH}\left({\text{CH}}_{\text{3}}\right){\text{CH}}_{\text{2}}\text{COOH}$ has to be given.

Concept Introduction:

Carboxylic acid consists of carboxyl group, which comprises of two functional groups namely carbonyl and hydroxyl group.

In carboxylic acid, the second oxygen atom is bonded to a hydrogen atom.

The compound $\text{R-COOH}$ is identified as carboxylic acid.

IUPAC naming of Carboxylic acids:

• The longest continuous carbon chain consisting of the carboxyl group i.e. the parent compound is determined.
• The carboxyl carbon is numbered as carbon-$\text{1}$.
• The –e ending of the parent alkane is replaced with suffix “–oic” acid.  If there are two carboxyl groups,–dioic acid is used as the suffix.
• The substituents are named and numbered.
