Question
What are electrophiles and nucleophiles? Explain with examples.

Answer

Electrophiles: The name electrophiles means electron loving. Electrophiles are electron deficient. They may be positive ions or neutral molecules.

Ex: H+, Cl+, Br+, NO2+, R3C+, RN2+, AlCl3, BF3

Nucleophiles: The name nucleophiles means ‘nucleus loving’ and indicates that it attacks the region of low electron density (positive centres) in a substrate molecule. They are electron rich they may be negative ions or neutral molecules.

Ex: Cl- Br-, CN-, OH-, RCR2-, NH3, RNH2, H2O, ROH etc.
