The HOMO of the
Concept introduction:
When atomic orbitals overlap during the formation of a molecule, an equal number of molecular orbitals (MOs) is formed. Half of these are bonding MOs, with energy less than the original AOs. The remaining half are antibonding MOs of energy higher (by almost the same amount) than the original AOs. The electrons from the overlapping atomic orbitals of the atoms fill up the MOs according to the Aufbau principle. In most cases, not all MOs are filled up. The highest energy MO with at least one electron occupying it is designated as the HOMO, Highest Occupied Molecular Orbital.

- Based on average bond enthalpies, would you expect a photon capable ofdissociating a C¬Cl bond to have sufficient energy to dissociate a C¬Br bond?arrow_forwardThe positions of the Br atoms in the molecule below is designated as Br -Br O meta O ortho O para O taroarrow_forwardThe vibrations of a CO2 molecule are symmetrical stretch, bend, and asymmetrical stretch (Figure ), with frequencies of 4.02x1013 s-1, 2.00x1013 s-1, and 7.05x1013 s-1, respectively. (a) What wavelengths correspond to these vibrations? (b) Calculate the energy (in J) of each vibration. Which uses the least energy?arrow_forward
- organic chemistry please solve questionnnnnnn 1arrow_forward4.) The dissociation energy of a carbon-bromine bond is typically about 276 KJ/mol. What is the maximum wavelength of photons that cause C---- Br bonds dissociation? and which kind of electromagnetic radiation--ultraviolet, visible, or infrared--does the wavelength you calculated correspond to? Group of answer choices A) 435 nm; Blue visible light B) 570 nm; Green/yellow visible light C) 7.2 x 10-31 m; gamma rays D) 435 nm; Red visible lightarrow_forwardThe s 3C molecule still has a lot of energy available. Where, specifically, is this energy located in this 3-carbon molecule?arrow_forward
- 44. The molecule H3* has long been speculated to exist. The interest here is that the addition of the smallest bit of nuclear matter, a proton, now introduces additional nuclear repulsion over the H₂ problem. The issue was whether electron distributions could lead to a stable configuration. a) Draw what you think would be the most stable structure for H3* and show all the Coulombic terms (write out the potential needed for the corresponding Schroedinger equation). b) Draw what you think is the least stable configure of the 3 protons and 2 electrons. c) It is found that the structure involves the rotation of one proton around the other two, and interchange of which proton is rotating. Offer a potential explanation (think tunneling).arrow_forwardWhen one electron is added to an oxygen molecule, a superoxide ion (O2-) is formed. The addition of two electrons gives a peroxide ion (O22-). Removal of an electron from O2 leads to O2+. (a) Construct the correlation diagram for O2-. (b) Give the valence electron configuration for each of the following species: O2+, O2, O2-, O22-. (c) Give the bond order of each species. (d) Predict which species are paramagnetic. (e) Predict the order of increasing bond dissociation energy among the species.arrow_forwarddarrow_forward
- Draw Lewis structures for each of the following ions. One atom in each ion has a formal charge that is not zero.Determine which atom it is, and what the formal charge is. (a) the C2H5 anion; (b) the CH3O cation; (c) the CH6N cation;(d) the CH5O cation; (e) the C3H3 anion (all three H atoms are on the same carbon)arrow_forwardMatch each of the following with its correct answer in the lewis structure for the CS, molecule, the number of unshared pairs of electrons on the central carbon is: The number of Tt bond (s) in the Lewis structure of NO- is An electron in the n= 6 level in hydrogen atomlemits a photon with a wavelength of 93.8 nm. To what energy level does the electron move The formal charge on nitrogen in the Lewis structure of NO+ is Ch The formal charge on oxygen in the Lewis structure of NO+ is Cho POCOPHONE SHOT ON POCOPHONE F1arrow_forwardIn particular, I'd appreciate help with part b of the problem. How does one compare the bond energies between identical elements if they don't have a chart with the numbers in front of them?arrow_forward
