    The absolute configuration of a stereoisomer has no necessary relationship with the direction it rotates plane-polarized light It is no simple proposition to determine the absolute configuration of any optically active isomer Early organic chemists KNEW that certain materials rotated plane-polarized light by a specific angle And how did they know this? Well Pasteur painstakingly separated
  • Please explain enantiomerisim and its condition? | Socratic
    A carbon atom with FOUR substituents, #CR_1R_2R_3R_4#, can exist as LEFT-HANDED or RIGHT-HANDED stereoisomers depending on the geometry The interchange of ANY TWO substituents results in the ENANTIOMER (and of course we do this on paper not in glass); interchange again, and you get the enantiomer of an enantiomer, i e the original isomer
  • How do you name alkenes with double bonds? + Example - Socratic
