Explain way draw the wedges and dashes when stereoisomers take place within a reaction mechanism. For example, a molecule such as cis-2-butene as well as trans-2-butene is reacting with H2O, H2SO4 or the molecule cis-2-butene as well as trans-2-butene reacting with Br, H2O. Explain is there a way to understand what goes on what wedges, dashes as well as lines out of the plane, behind the plane and in the plane?
