Problem 4. Consider these M iagrams for HE and HI. Note that the orbitals for the lone pairs on the the dtoms are omitted. Therefore, you see only ! valence electron shown for the fluorine atom and the iodine atom instead of 7 valence electrons for the F and the I atoms. Antibonding MO Anibonding MO 15p E H 1s H 1s F 2p Bonding MO Bonding MO H-F: Hi: a) Why does it make sense that the fluorine 2p atomic orbital is at a lower energy than the iodine Sp atomic orbital? Explain your answer. b) Draw a picture of the bonding MO of HF. How many nodes are there in this MO? C) The H-I bond is weaker (casier to break) than the H-F bond. Explain this observation, with refercnce to lhe MO diagans alaown al die top of this page.
