Chapter 9.SE, Problem 28AP

Interpretation Introduction

a)

Interpretation:

The hydrocarbon shown is isolated from sun flower family. It is to be named following the IUPAC rules.

Concept introduction:

The longest carbon chain which contains the carbon-carbon triple bond is chosen. The chain is numbered from the end that gives the lowest number to the carbon in triple bond. Compounds with more than one triple bond are called diynes, triynes and so forth. Compounds containing both double bond and triple bonds are called as enynes. The chain is numbered from the end nearer to the multiple bonds, double or triple. When there is a choice in numbering the double bond is given preference and the lowest number is assigned to it.

To name:

The hydrocarbon shown, isolated from sun flower family, according to the IUPAC rules.
