BF_(3) is

1.	BF_(3) is
Answer» Electron - DEFICIENT compound LEWIS ACID USED as rocket fuel Ionic compound Solution :`underset("Ground state")(B)-2s^(2)2p^(1)` `underset("EXCITED state")(B)-underset(sp^(2))(ubrace(2s^(1)2p_(x)^(1)2p_(y)^(1))) 2p_(z)^(0)` Since the octet asround B is incomplete, it behaves as an electron - deficient compound. `BF_(3)` can accept a pair of electron from some other ion/molecule in vacant 2p orbital and thus behave as a Lewis acid.
