The first substitution takes place rapidly at room temperature. The second substitution takes place near 100 °C, and the third substitution requires even higher temperature and pressure.

The center of positive charge "loves" regions with high electron density and Aus called electrophiles. When an atomic center possesses an excess of negative charge, it is more Ay to react with centers with an excess of positive charge. The center of negative charge "loves" egions where the nuclear charge is less shielded and are thus called nucleophiles. Generally, labelling a center as nucleophilic or electrophilic requires a fair amount of excess charge on that center and poor stabilization of the charge. Note that while the charge distribution on a molecule is a strong driver of how it will react, there are other factors that also matter. 7) For each molecule below, label any nucleophilic or electrophilic centers.
