same atoms, different swagger — chemistry's proof that arrangement is everything.
means An isomer is one of two or more molecules that share the same chemical formula — the same atoms in the same numbers — but differ in how those atoms are connected or arranged in space, giving them distinct properties.
from Coined in the 19th century from the Greek 'isos' (equal) and 'meros' (part) — literally 'equal parts.' The Swedish chemist Jöns Jacob Berzelius is credited with introducing the term as chemists realized, to their puzzlement, that substances with identical composition could behave like complete strangers. The 'meros' here is the same building-block root that shows up in 'polymer' (many parts) and 'merit'-free relatives like 'merology'.
- same formula
- identical atom count, wildly different molecules
- taste twist
- one isomer smells of oranges, its mirror of lemons
- thalidomide tragedy
- one form cured, the mirror form deformed babies
- count explosion
- C40 alkanes have over 60 trillion possible isomers
- mirror trap
- enantiomers can't be superimposed, like your hands
glucose and fructose — both c6h12o6 but glucose is aldohexose while fructose is ketohexose
ortho meta para xylene — three isomers of c8h10 differing in benzene ring methyl group positions, used in industrial production
cis trans butene — c4h8 with same atoms but different spatial arrangement around double bond, different boiling points
