Which of the following statements concerning the fundamental nature of isomerism are correct? — Isomerism and Stereochemistry Chemistry Question

💡 Solution & Explanation

Statements A, B, and C are correct. Berzelius introduced the term in 1830. Entropy (a thermodynamic system property) plays a role in the formation of isomers to stabilize a system. Since isomers have the same molecular formula, their empirical formula and molecular weights are identical. Statement D is incorrect; the JEE trap is assuming a molecule itself is an isomer. Isomerism is a relational property between a pair (or more) of molecules.
