Nucleophiles and Electrophiles Flashcards
What is the definition of a nucleophile?
A chemical species with an electron rich atom that is capable of donating a pair of electrons
What is the definition of an electrophile?
A chemical species with an electron deficient atom that is capable of accepting a pair of electrons
What is the symbol for a nucleophile?
Nu
What is the symbol for an electrophile?
E
Explain the flow of electrons.
Electrons flow from “electron rich” areas (nucleophiles) to “electron poor” areas (electrophiles)
What are nucleophiles often referred to as?
Electron rich areas
What are electrophiles often referred to as?
Electron poor areas
What is formed when a Nu and an E react together?
A new covalent bond is formed
Describe the charge of a nucleophilic site.
A nucleophilic site typically has a partial negative charge (or fully negative charge making it an anion)
Describe the charge of an electrophilic site.
it can be a neutral species or have a partial or full positive charge (cation)
In relation to pH what is a nucleophile?
Its a Lewis base
In relation to pH what is an electrophile?
Its a Lewis Acid
