How can you tell when a reaction goes through the meisenheimer complex or benzyne? (The Meisenheimer complex is formed only in the presence of a resonance acceptor in an ortho- or para-position to the leaving group. Otherwise the reaction requires a strong base, harsher conditions, and proceeds through benzyne - GS).

Can you explain in more detail the separation of enantiomers into diastereomers? (A mixture of enantiomers is treated with a chiral reagent to convert them to two new compounds, which have opposite centers from enantiomers and same centers from the chiral reagent, so they are diastereomers. Next, the diastereomers are separated and cleaved back into original enantiomers and the chiral reagent back. - GS).
