Question
3. The molecule BF has such a large energy difference between B and F that the
2s orbital of boron combines with the 2pz orbital on F. The remaining 2p orbitals on
fluorine combine with two of the 2p orbitals on boron to form pi orbitals. The third 2p
orbital on boron is nonbonding. The energy ordering of the molecular orbitals is (2sF) <
4(2sg + 2pf) < Þ(2pg - 2pf) < y(2sg-2pf) < (2pg + 2pf) < (2pB)
a. Draw the molecular orbital energy diagram for BF.
b. Determine the bond order of BF. Is it paramagnetic?
