Tautomerism is a broad dynamic phenomenon encompassing several specific chemical systems. Which of t — Isomerism and Stereochemistry Chemistry Question

💡 Solution & Explanation

Nitro-acinitro and lactam-lactim are classic examples of 1,3-shift triad tautomeric systems. Hydrogen cyanide and isocyanide represent a 1,2-shift diad tautomeric system where a proton oscillates rapidly. However, primary alcohols and ethers are purely static functional isomers; their structural conversion demands breaking strong $C-O$ and $C-C$ bonds, preventing them from existing in rapid dynamic equilibrium.
