Basicity rules - -strong base: unstable/reactive (ED groups) -weak base: stable (EW groups/more EN/bigger) Chair conformation - -more stable equitorial (slanted) -pointing up/pointing down=cis if both up -elimination: trans and diaxial Newman projection - -gauche: substituent groups adjacent to eachother -grab middle and turn to put in plane Enantiomers - -not superimposable mirror images -same besides stereochemistry Diastereomers - -mirror images but one stereocenter stays and...
