Chapter 17, Problem 17.83AQAP

Interpretation Introduction

(a)

Interpretation:

The IUPAC name of the given compound should be determined.

Concept Introduction:

In order to give the IUPAC name to the alcohol following steps are followed:

1. The parent (longest) alkane chain is identified.

2. The ending of the parent chain from alkane (-e) is changed to -ol and the number is used to locate the -OH group of alcohol.

3. Name should be written in alphabetical order and numbering should be done in such a way that hydroxy group gets lowest number.

4. Configuration should be specified is there exist any cis-trans isomerism.

For number of carbons atoms in chain, the prefix is given as:

Carbon-1  meth

Carbon-2  eth

Carbon-3  prop

Carbon-4  but

Carbon-5  pent

Carbon-6  hex

Carbon-7  hept

Carbon-8  oct

Carbon-9  non

Carbon-10  dec

Interpretation Introduction

(c)

Interpretation:

The common names of the given compound should be determined.

Concept Introduction:

When the oxygen atom is connected to two alkyl or aryl groups with general formula R-O-R’ such class of compounds is known as ether.

The common name of ether with low molecular weight ethers are derived by listing the alkyl groups bonded to oxygen in alphabetical order and then ending with word ether.
