Concept introduction:
Molecular orbitals are constructed from the AOs of different atoms. When two atoms are brought close enough together (i.e., about a bond length apart), the AOs of one atom significantly overlap the AOs of the other atom, enabling them to undergo constructive and destructive interference or mix, to produce new orbitals called MOs. When AOs undergo mixing to produce new MOs, there are equal numbers of bonding and antibonding orbitals, and the remaining orbitals are represented by nonbonding orbitals. In carbocation, the positively charged carbon is

- One of the orbital interactions we did not consider in this chapter is that between an s AO from one atom and a p AO from another atom in the fashion shown. These orbitals will not interact while in this orientation. Explain why.arrow_forwardConstruct, fully label, and populate a MO diagram for the nitrosonium anion, NO+. Based on the diagram, state which of NO+ or NO you expect to have a stronger bond.arrow_forwardplease answer this spec question and let me know what molecule/structure it is!arrow_forward
- Let us construct the molecular orbital diagram of ethylene (in pieces). a. First, construct the MO diagram of linear carbene (CH2). Draw pictures of all 6 orbitals b. Now bend the carbene to a bond angle of about 120°. How does this change your MO diagram? Draw pictures of all 6 orbitals. c. Now bring two of these carbene molecules together to make ethylene. Draw pictures of all 12 orbitals.arrow_forwardQ1. Please answer the following questions with respect to this structure. но. a) What is the hybridization of all atoms in the molecule? b) There are two double bonds in the molecule. For each, indicate the correct stereochemistry, by circling E or Z.arrow_forwardPlease construct the MO diagrams of NH3 and NH4+and use their MO’s toexplain the protonation (acid-base reaction) of NH3arrow_forward
- Draw a bond-line structure that best matches the given 3D representation?arrow_forwardThe partial Lewis structure below is an example of an amide functional group, which we will learn about in the next chapter. What is the hybridization and geometry of the methyl (CH3) carbon? What is the hybridization and geometry of the central carbon? (Note: the structure below is intended to show connectivity only - the geometry as drawn is not representative of the true structure!) CH3–C-NH, Next Previousarrow_forwardA chair structure of a disubstituted cyclohexane is shown below. Determine which of the following 2D representations matches the chair structure. II A) I CH3 CH3 CI B) II C) II II CH3 IV H3C CI D) IV CI S..arrow_forward

(a) CH3CN (b) CH₂=CHCH₂CH=Oarrow_forwardPlease show all steps and I will upvote if correct. According to the Walsh diagram, why is NH3 pyramidal while BH3 is planar? Which molecule should have the smallest bond angle ~ NH3, PH3, or AsH3? Think of electronegativity differences and the Walsh diagrams of these molecules.arrow_forward
