Chapter 20.11, Problem 20.6SC

Interpretation Introduction

Interpretation:

The IUPAC names of the given alcohol and whether it is primary, secondary or tertiary should be determined.

Concept Introduction:

When alcohol (having hydroxyl group) is attached to a primary carbon atom (carbon atom to which one carbon atom is attached) then such alcohol is said to be a primary alcohol.

When alcohol (having hydroxyl group) is attached to a secondary carbon atom (carbon atom to which two carbon atoms are attached) then such alcohol is said to be a secondary alcohol.

When alcohol (having hydroxyl group) is attached to a tertiary carbon atom (carbon atom to which three carbon atoms are attached) then such alcohol is said to be a tertiary alcohol.

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.
