Chapter 17.1, Problem 9PP

(a)

Interpretation Introduction

Interpretation: The IUPAC name of the following compound should be determined:

Concept Introduction:

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

1. The parent (longest) continuous carbon chain is identified.

2. The ending of the parent chain for alkane (-e) is -ane.

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

4. Hyphen is used to connect the number to the name.

For number of carbons atoms in alkane 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

Interpretation: The IUPAC name of the following compound should be determined:

Concept Introduction:

In order to give the IUPAC name to the branched-chain alkane following steps are followed:

1. The parent (longest) continuous carbon chain is identified.

2. The ending of the parent chain for alkane (-e) is -ane.

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

4. Hyphen is used to connect the number to the name.

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