Chapter B, Problem B.25P

Interpretation Introduction

Interpretation:

The correct IUPAC name for $\text{2-propylbut-1-ene}$ is to be written.

Concept introduction:

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