Question

15. BFO is isoelectronic and isostructural with CO2 discussed in CH225 Lecture 17. On the basis of this consideration, respond to the following: (a) Sketch the two group orbitals involved in o-bonding in BFO. F во FB 0 (b) For one of the above group orbitals, sketch its bonding combination with a p orbital of boron. F в о (c) Sketch a T* MO of BFO. Е в о (d) Tell the numbers of valence electrons in the following molecules and ions; select all species isoelectronic with BFO: NCO-, CIO2, N3-, N20, F20, NO2
