- (a) Draw an energy diagram for the cyclopropenyl MOs. (The polygon rule is helpful.) Label each MO as bonding, nonbonding, or antibonding, and add the nonbonding line. Notice that it goes through the approximate average of the MOs.(b) Add electrons to your energy diagram to show the configuration of the cyclopropenyl cation and the cyclopropenyl anion. Which is aromatic and which is antiaromatic?arrow_forward(a) Use the polygon rule to draw an energy diagram for the MOs of a planar cyclooctatetraenyl system. (b) Fill in the eight pi electrons for cyclooctatetraene. Is this electronic configuration aromatic or antiaromatic? Could the cyclooctatetraene system be aromatic if it gained or lost electrons? (c) Draw pictorial representations for the three bonding MOs and the two nonbonding MOs of cyclooctatetraene. The antibonding MOs are difficult to draw, except for the all-antibonding MO.arrow_forwardGive a clear handwritten answer with explanation....given below some compounds choose which compound is contains sp2 hybridized carbon atom...?arrow_forward
- AnillaceIle is Complete the structure for anthracene, C,,H. by adding bonds and hydrogen atoms as necessary. Select Drow Rings More Erase What type of hybrid orbitals are utilized by carbon in anthracene? How many o bonds and x bonds are there in an anthracene molecule? G bonds: I bonds: How many valence electrons occupy o-bond orbitals, and how many occupy x-bond orbitals? valence e in a-bond orbitals: valence e- in x-bond orbitals:arrow_forward. Draw a representation for the n-electron Frontier Molecular Orbitals of the following compounds. Consider whether the ground state or excited state is represented. a) b) HO, (ground state) (excited state) # of a electrons: # of electrons: # of overlapping p-orbitals: # of overlapping p-orbitals:arrow_forwardDraw a representation for the n-electron Frontier Molecular Orbitals of the following compounds.

- Describe the ground-state electron configuration of the cyclopentadienyl cation, radical and anion. Would you expect each species to be aromatic, antiaromatic, or non-aromatic? (Hint: Use a Frost circle to illustrate MO energy levels diagram).arrow_forwardCircle any of the following which you think are aromatic systems. For the ones that are aromatic systems, give the "n" (Huckel number.) It's possible tk have more than one. Thank you!arrow_forwardAnswer the following questions for 1,3,5- hexatriene, the conjugated triene containing six carbons.Which MOs are bonding? Which are antibonding?arrow_forward
- Considering all the structures as planar, classify the molecules aromatic and non-aromatic.arrow_forwardIsn't the carbon where the charge changes sp3 hybridized? Wouldn't that make them all non-aromatic? Also, do we need to specify E and Z for the double bonds. Thanks.arrow_forwardO Use the polygon rule to draw the MO energy diagram of the cyclononatetraenyl anion. Assuming planarity, would this ion be aromatic or antiaromatic?arrow_forward
