Question
The optical activity of a fat depends on its structure. Draw two fat structures that each yield stearic acid (2 molar equivalents) and oleic acid (1 molar equivalent) on hydrolysis:(a) an optically active fat;(b) an optically inactive fat.

Evidence boundary
This addresses both drawing tasks in OpenStax Organic Chemistry Problem 27-18. The drawings are original representations with fully defined tails, not a copied answer key. “Optically active” assumes an enantiomerically enriched sample of the chiral structure; the problem supplies no experimental rotation, so neither its sign nor magnitude is assigned. Hydrolysis proportions alone do not establish acyl positions or enantiomeric composition.
