Chapter 17.2, Problem 17.14QAP

Interpretation Introduction

(a)

Interpretation:

The IUPAC name of the given compound should be determined.

Concept Introduction:

The hydrocarbon compounds that is compound containing only hydrogen and carbon atoms that contains multiple bond(s) are said to be unsaturated hydrocarbon. Compounds containing double bonds are said to be alkene whereas compounds containing triple bonds are said to be alkyne.

In order to give the name to the unsaturated hydrocarbon following steps are followed:

1. The parent (longest) continuous carbon chain containing multiple bonds between the carbon atoms is selected.

2. While writing the name of alkene, the suffix “ane” of the corresponding alkane is replaced by “ene”.

3. Name should be written in alphabetical order and numbering should be done in such a way that the multiple bond and 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
