Derive the MO diagram of a linear C-H (i.e. one carbon atom bonded to one hydrogen atom). Draw out the MOs for orbitals containing electrons Would you expect C-H to behave as a carbocation, carbanion, or radical? Would removal of one electron from C-H to generate C-H+ increase or decrease the bond length between carbon and hydrogen?arrow_forward5-3. a. Draw out an empty generic (lollipop shaped) homonuclear diatomic MO diagram like the one used for O2, F2, and Nez. b. Fill this diagram with the appropriate number of valence electrons for [NO]¹ and use it to write out the MO electron configuration for [NO]¹-ion. c. What is the N-O bond order in [NO]¹? d. Will the N-O bond in [NO]¹ be longer or shorter than the N-O bond in the neutral NO molecule? e. How many unpaired electrons are present in [NO]¹? f. Will the unpaired electrons be more concentrated on N or O in [NO]? Explain.arrow_forward
