A reaction between ammonia and BF3 is given below. :NH3+BF3 gives H3N:BF3 identify the acid and base in this reaction which theory explain it

Solution

NH₃ has lone pair of electron on nitrogen atom while in BF₃ boron has empty 2p orbital where it can except electron. so it will except electron from NH₃. ACCORDING to lewis chemical species with capability of donating electron are base and those who have capability of accepting electron are acids . by the defination we get to know that NH₃is base and BF₃ is and acid forming adduct
