Which оf the fоllоwing is the electron configurаtion of аn excited stаte of an oxygen atom?
Whаt mаjоr clаss оf biоmolecule is in each of these pharmaceuticals or consumer products? If a lipid, specify the subclass. Click to Show Image Description The structure is labeled “levodopa” and shows a six-carbon benzene ring with two HO groups bonded to adjacent carbons on the left side of the ring. A carbon chain extends from the right side of the ring to a carbon shown with a solid wedge bond to NH₂ and a single bond to a carbonyl carbon. The carbonyl carbon is double bonded to O and single bonded to OH. [classA] Click to Show Image Description The structure is labeled “Nasonex” and shows a multi-ring skeletal chemical structure with fused rings in the center and lower left. An HO group is bonded to the upper-left part of the fused-ring system. Cl appears on a lower central ring carbon and again at the end of a short side chain on the upper right. The structure also includes two C=O groups, one on the lower-left ring and one in the upper-right side group, plus a five-membered oxygen-containing ring attached near the top. Solid wedge and dashed wedge bonds indicate three-dimensional bond orientation. [ClassB] Click to Show Image Description The structure is labeled “δ-cadinene - oil of juniper” and shows two fused six-carbon rings sharing a central bond. A C=C bond appears on the upper-left side of the left ring. Solid wedge bonds extend to one-carbon branches on the lower-left ring carbon and the upper ring junction. Another solid wedge extends from the lower ring junction to a branched carbon group with two one-carbon ends. [ClassC] Click to Show Image Description The structure is labeled “Didanosine (phosphate) treatment of HIV.” A five-membered ring containing one O atom is connected on the left to a phosphate group and on the right to a fused two-ring structure containing several N atoms. The phosphate group shows P double bonded to O, single bonded to two OH groups, and single bonded through O to the five-membered ring. The fused ring system includes a C=O group at the upper right and an N-H group at the lower right. Solid wedge bonds indicate three-dimensional bond orientation at two points on the five-membered ring. [ClassD]
