Chapter 24, Problem 24.59QP

a)

Interpretation Introduction

Interpretation:

The structure of the alkane cyclopentane has to be predicted.

Concept introduction:

IUPAC Nomenclature of cycloalkanes:

The longest continuous ring of carbon atoms is identified. The prefix is added with ‘cyclo’.

The substituent groups attached to the parent chain is identified. A substituent group contains group of atoms attached to the carbon atom of the chain.

While numbering the longest chain, the substituent should get least possible number.

Write the name of the compound; the parent name written as last part of the name. The name of the substituents is written as prefix and a hyphen separates the number that the substituents attached with carbon. More than one substituent should be written in alphabetical order.

a)

Expert Solution

Explanation of Solution

Given name: cyclopentane

Predict the longest continuous chain of carbon atoms:

The parent name is CYCLOPENTANE represent the continuous ring of carbon atoms contains five carbons. The Suffix ‘ane’ represents the structure contains only single bonds.
