Boron Trifluoride and Ammonia (Lewis Acid-Base)

概述

Boron trifluoride, a classic Lewis acid with an empty p-orbital on boron, accepts an electron pair from ammonia's lone pair to form a dative bond. No proton transfer occurs, making this purely a Lewis acid-base reaction. The product is a stable adduct where boron achieves an octet.
