CHEM 210 Lecture Notes - Lecture 22: Electrophile, Hydrogen Bond, Pi Bond
Document Summary
Chem 210: structure and reactivity - lecture 22: review before exam 2. Pi bonds break, h+ and anion attach to either end. The more stable product will be formed from the anion attaching to the most stable carbocation (attached to the most carbons). On an sp3 carbon, the leaving group ( electrophile") will be replaced with an electron heavy nucleophile. ". One sided attack : stereochem is reversed (forward to back, back to forward). Major conformation is the one where the major substituents are in the equatorial position. On down" chair points, equatorial position is the higher one. On up" chair points, equatorial position is the lower one. Anti: major groups are across from each other. Gauche: major groups are next to each other.
