Chapter B, Problem B.24P

Interpretation Introduction

(a)

Interpretation:

IUPAC name for the molecule is to be written.

Concept introduction:

For naming an alkene or alkyne, the longest continuous carbon chain is the one that contains $\text{C=C or C}\equiv \text{C}$ bonds. To assign the root, begin with the name of the analogous alkane and replace the suffix by ‘ene’ or ‘yne’ The suffix ‘ene’ accounts for a $\text{C=C }$ functional group while ‘yne’ accounts for a $\text{C}\equiv \text{C }$ functional group. For a chain, C1 begins at the end that allows $\text{C=C or C}\equiv \text{C}$ bonds the lowest possible locator numbers. For a chain, the lowest locator numbers are written immediately before the ene or yne suffix.
