the.com/stereoisomerism
Same atoms, same bonds, same address — different furniture arrangement, totally different life.
means The phenomenon where molecules share an identical molecular formula and identical bonding sequence but differ in the three-dimensional arrangement of their atoms in space, often giving them very different chemical or biological behavior.
from Built from Greek pieces: 'stereo-' from stereos, meaning 'solid' or 'three-dimensional' (the same root that gives us stereo sound and stereoscopic vision), plus 'isomer,' itself from isos ('equal') and meros ('part/share') — so an isomer is something made of equal parts, same composition, just arranged differently. Chemists in the 1800s, puzzling over compounds that were identical on paper but behaved differently in the lab (rotating light differently, reacting differently), needed a word for 'same parts, different shape in space' — stereoisomerism named exactly that spatial twist.
