The game focuses on the SN2 reaction, which is often one of the first reactions students learn when studying organic chemistry. Witryna8 sie 2012 · Since the S N 2 proceeds through a backside attack, if a stereocenter is present the S N 2 reaction will give inversion of stereochemistry. By contrast, if the S N 1 leads to the formation of a stereocenter, there will be a mixture of retention and inversion since the nucleophile can attack from either face of the flat carbocation.
