Nobel Prize in Chemistry 2026: Mirror-Image Molecules & Chirality

The 2026 Nobel Prize in Chemistry is being jointly awarded to two scientists, Henri B. Kagan of France and Kenzo Soai of Japan.

This award has been given for their research on the enigmatic 'Mirror-image molecules' (Chirality) in Chemistry and the spontaneous formation of molecules with linear properties (Asymmetric Autocatalysis).

🎯 TNPSC Exam Key Notes:

• 2026 Chemistry Nobel Winners: Henri B. Kagan (France) and Kenzo Soai (Japan).
• Research Field: Mirror-image molecules (Chirality), Asymmetric Synthesis & Soai Reaction.
• Chiral Carbon Atom: A carbon atom bonded to four different atoms or groups.
• Asymmetric Autocatalysis: The primary product formed in the reaction itself acts as a catalyst to further proliferate the same chiral configuration.
• Medical Significance: In drug molecules, only a specific enantiomer provides therapeutic relief; the wrong image could cause side effects.

📌 KEY FOR TNPSC:

• 2026 Chemistry Nobel: Henri B. Kagan (France) & Kenzo Soai (Japan) - Chiral Molecules (Chirality).
• Instrument used to measure optical isomers: Polarimeter.
