The reaction between ( C H 3 ) 2 N H and boron trifluoride is to be written by using the curved-arrow notation. In the reaction, Lewis base, Lewis acid, electrophile, and nucleophile are to be identified and formal charges are to be assigned. Concept introduction: Lewis acids are electron pair acceptors. Lewis bases are electron pair donors. Any electron deficient species can act as a Lewis acid such as compounds containing group IIIA elements like Boron or Aluminum. Compounds having vacant orbitals also act as Lewis acids like halides of Iron, Zinc and Aluminum. Electron loving or seeking compounds are called Electrophiles. All Lewis acids are electrophiles but all electrophiles are not Lewis acids Electron donating compounds are called Nucleophiles.
