Interpretation Introduction

Interpretation:

The structure of stearolic acid (C₁₈H₃₂O₂) which on catalytic hydrogenation yields stearic acid and upon treatment with ozone gives nonanoic acid and nonanedioic acid is to be proposed.

Concept introduction:

Catalytic hydrogenation reduces double bond and triple bonds in unsaturated compounds to yield saturated compounds. During ozonolysis double bonds are cleaved to yield carbonyl compounds while triple bonds are cleaved to yield carboxylic acids.

To propose:

The structure of stearolic acid (C₁₈H₃₂O₂) which on catalytic hydrogenation yields stearic acid and upon treatment with ozone gives nonanoic acid and nonanedioic acid.
