MCAT Chemical and Physical Foundations of Biological Systems Flashcards: 5b Stereochemistry Isomerism

Study 5b Stereochemistry Isomerism in MCAT Chemical and Physical Foundations of Biological Systems with focused flashcards that help you recognize the idea, recall the key rule, and apply it in practice-style prompts.

QUESTION

In cyclohexane, which chair substituent position is generally more stable for bulky groups: axial or equatorial?

Tap card or press Space to flip

ANSWER

Equatorial (minimizes $1,3$ -diaxial interactions). Equatorial positions reduce steric hindrance from 1,3-diaxial interactions in chair forms.

A retinal-analog probe exists as geometric isomers about a C=C bond: Molecule C (cis) and Molecule T (trans). In a membrane-binding assay, Molecule T shows higher partitioning into lipid bilayers, while Molecule C shows reduced packing compatibility. Which statement best describes the stereochemical basis for the observed difference?
