Chapter 4, Problem 4.24YT

(a)

Interpretation Introduction

Interpretation:

The structure of a saturated molecule that corresponds to the given unsaturated molecule is to be drawn.

Concept introduction:

Each saturated organic molecule must have general formula with single bonds only with no ring in their structure. So the saturated molecule contains the maximum number of hydrogen atoms with a formula like an alkane, ${\text{C}}_{\text{n}}{\text{H}}_{\text{2n+2}}$, for hydrocarbon only. The index of hydrogen deficiency (degree of unsaturation) corresponds to the number of hydrogen atoms missing from the compound. If IHD of the given molecule is one, it means the molecule must have either one double bond or a ring with two hydrogens less than its corresponding saturated structure.
