Step 1

Given chemical reaction 1 is:

According to Lewis acid-base theory, Lewis acids are electron-pair acceptors while Lewis bases are electron-pair donors.

Lewis acid accepts an electron from Lewis base and forms an adduct.

In the given reaction 1, NH3 contains a lone pair of electrons and acts as a Lewis base.

BF3 possesses the only six electrons in its outermost orbitals and hence it can accept a pair of the electron from ammonia to complete its octet.
