- Give a clear handwritten answer with explanation....given below some compounds choose which compound is contains sp2 hybridized carbon atom...?arrow_forwardWhich of the following species is NOT aromatic? (Assume that if the molecule/ion can be planar in order to meet the criteria for aromaticity then it will be). o omarrow_forwardAnillaceIle 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 n electrons: # of : electrons: # of overlapping p-orbitals: # of overlapping p-orbitals: LUMO LUMO НОМО НОМОarrow_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_forwardDescribe 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_forward
- Circle 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_forwardConsidering all the structures as planar, classify the molecules aromatic and non-aromatic.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
- O Use the polygon rule to draw the MO energy diagram of the cyclononatetraenyl anion. Assuming planarity, would this ion be aromatic or antiaromatic?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_forwardRizatriptan (trade name Maxalt) is a prescription drug used for the treatment of migraines. (a) How many aromatic rings does rizatriptan contain? (b) Determine the hybridization of each N atom. (c) In what type of orbital does the lone pair on each N reside? (d) Draw all the resonance structures for rizatriptan that contain only neutral atoms. (e) Draw all reasonableresonance structures for the ve-membered ring that contains three N atoms.arrow_forward
