Nucleophilic center (nucleophile) is an electron-rich atom that is capable of donating a pair of electrons to another atom. They like to react with atoms that either have a Positive charge or a partially positive charge (+). They typically have either a Negative formal charge or a partially negative charge ()OR are a multiple bond (area of build-up of electron density). Q6) Identify the atom(s) in the following molecule that are nucleophilic centers. Electrophilic center (electrophile) is an electron-poor atom that is capable of accepting a pair of electrons from another atom. They like to react with atoms that have lots of electrons that they want t share (either Negative charges, partially negative charges, or multiple bonds). They typically have eithe a Positive formal charge or a partially positive charge (+). Q7) Identify the atom(s) in the following molecules that are electrophilic centers. (Hint: You might hav to consider resonance structures sometimes)
