- Alkyl diazonium salts (shown below) are considered "super" leaving groups; a consequence of this is that they tend to be contact explosives What quailities make alkyl diazonium salts such excellent leaving groups?Which nucleophiles will add to the following conjugated enone at the A carbon? Which will add at the B carbon?des and Nucleophiles atomic center possesses an excess of positive charge, it is more likely to react with regions with ess of negative charge. 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. Briefly explain your reasoning. a) b) c) OH Li NH₂ d) e) f) NⓇH -N- on nucleophilic strength. 8) For each molecule below, predict…
