padilla (tp5647) – Homework 6 – Sutcliffe – (53770)6and B2, one valid difference is that1.B2has a total of 10 electrons; HF has atotal of 11 electrons.2.the atomic orbitals of hydrogen are lowerenergy than those of fluorine.In the B2molecule, both atomic orbitals are of equalenergy.3.delocalization of electrons occurs in B2,but not in HF.4.B2has no non-bonding electrons, but HFdoes have nonbonding electrons.correctExplanation:Both HF and B have 10 electrons, noneof which are delocalized.In HF the atomicorbitals of the more electronegative F aredrawn lower than H. Non-bonding electronsare found in HF but not in B2.02210.0 pointsMolecule1,aheteronucleardiatomicmolecule, has 8 bonding electrons, 16 non-bonding electrons, and 6 anti-bonding elec-trons.Molecule 2, a heteronuclear diatomicmolecule, has 2 bonding electrons, 12 non-bonding electrons and 0 anti-bonding elec-trons. Which molecule is more stable?02310.0 pointsConsider the diatomic molecules CO, whichhas a bond order of 3, and O2, which has abond order of 2. One can state that O2wouldbe (easier, harder) to break apart than CO,and would also have (longer, more, shorter)bonds than CO.
