Picture (2) correctly represents the initial Lewis acid-Lewis base interaction, where BF₃ acts as the Lewis acid and NH₃ acts as the Lewis base. This is because BF₃ has a vacant orbital that can accept a pair of electrons from the lone pair on one of the nitrogen atoms in NH₃, forming a coordinate covalent bond.
