    Structural isomers - already have different names following the IUPAC laws of nomenclature
    Methyl propane vs Butane (both C4H10)

    Stereoisomers - isomers that differ by spatial orientation

    Optical Isomers - two mirror images of the same molecule with different chirality a.k.a. enantiomers]]>     2023-02-09 00:49:13 UTC https://padlet.com/hikae/xly126ilrsxqgjff/wish/2474278333     Stereoisomers hikae https://padlet.com/hikae/xly126ilrsxqgjff/wish/2474279312 Because of double bonding, the two molecules will never be identical.

  • Chiral molecules, (carbon with 4 attached groups)
  • to differentiate the enantiomers, use R/S system

    • R/S nomenclature
    lowest priority is pointed away
    other three groups priority ordered
    if decreases clockwise, R
    if decreases counterclocwise, S

    Priority rules:
    Higher atomic number (Cl > H)
    Higher atomic number at distance 2
    Repeat until tie broken
