Document Summary

__ e. be: order the elements s, cl, and f in terms of increasing atomic radii. Electrons are never found in an antibonding mo. All antibonding mos are higher in energy than the atomic orbitals of which they are composed. __ c. antibonding mos have electron density mainly outside the space between the two nuclei. __ d. none of the above is true. X_ e. two of the above statements are true. (b and c) Ch141 practice exam 3: in one sentence, clearly explain why co has a small bond dipole (polar compound) and the oxygen has a partial positive charge. You can draw a picture to support your answer. Although oxygen is more electronegative than carbon, co has a +1 formal charge on o and a -1 formal charge on c, which causes a slight bond dipole toward the c. C o: in one sentence, clearly explain why mgo has a much higher lattice energy than naf.
