Subject-Specific FAQs

Q: How are Gibbs Free Energy calculations different from enthalpy calculations in this course?

Gibbs Free Energy (ΔG) combines enthalpy (ΔH) and entropy (ΔS) to predict spontaneity (ΔG = ΔH TΔS), whereas enthalpy alone only accounts for heat exchange. This course emphasizes ΔG for equilibrium predictions, especially in redox and acid-base reactions.

Q: Why is stereoisomerism important in functional group chemistry?

Stereoisomerism (e.g., cis-trans in alkenes, R/S in chiral centers) affects biological activity, reactivity, and physical properties (e.g., optical rotation). This unit covers IUPAC rules for naming and predicting stereochemical outcomes in reactions.
