Answer to Question #24527 in Organic Chemistry for shafiqah asim
explain hybridization in BF3
The ground state electronic configuration of boron is 1s^2 2s^2 2p^1
B ground state & I& i!& I I i I & I I
B exited state I& i!& I I i& I i I I
Because, of sp2 hybridization, BF3 has triangular planar shape.
