Chapter 7, Problem 32P

Interpretation Introduction

Interpretation:

Structural formula for each alkene of molecular formula ${\text{C}}_{\text{7}}{\text{H}}_{\text{14}}$ that has a tetra substituted double bond is to be written, and two acceptable IUPAC names are to be discussed.

Concept introduction:

An alkene having a tetra substituted double bond has four carbon atoms directly attached to the $\text{C=C}$.

The alkene corresponding to the longest continuous chain that includes the double bond is considered as the parent, and the chain is numbered in the direction that gives the doubly bonded carbons their lower numbers.

The locant (or numerical position) of only one of the doubly bonded carbons is specified in the name.

According to various versions of the IUPAC rules, the locant may precede the parent chain or the $\text{-ene}$ suffix.
