A reaction between ammonia and boron trifluoride is given below:
Identify the acid and base in this reaction. Which theory explains it? What is the hybridisation of B and N in the reactants?
As per the information given in the question,
is the Lewis acid in this reaction because it has a lone pair of e- to donate in its p-orbital. Moreover, the Lewis base in this case is BF3 as p-orbital of Boron is empty. As such, it will be accepting lone pair from N to form a dative bond, as is clear from the lewis electronic theory. Thus, the Hybridisation of N is sp3 and B is sp2.
