1.	A reaction between ammonia and boron trifluoride is given below: NH_3 + BF_3 to H_3N :BF_3 Identify the acid and base in the given reaction. Which theory explains it? What is the hybridisation of B and N in the reactants ?
Answer» Solution :As `BF_3` does not have a PROTON but acts as LEWIS acid as it is an electron deficient molecule. It reacts with `NH_3` by accepting the lone pair of electrons from `NH_3` and COMPLETE its octet. The reaction is `BF+:NH_3 to BF_3 larr NH_3` Lewis theory of acids and bases can EXPLAIN it. BORON in `BF_3` is `sp^2` hybridised where N in `NH_3` is `sp^3` hybridised.
