The chemical formula for each of the given coordination complexes is to be written. Concept Information: Complex ions are ions formed by a metal atom at their center such that, other nonmetal molecules or ions surround it. Ligands are molecules or ions that are bonded to a metal ion with a coordinate covalent bond. Coordination complexes are complexes that are formed by a coordinate covalent bond between ligands and metals. To write the formula for a complex, following rules are utilized: The symbol for the metal ion is always given first, followed by the ligands. When more than one kind of ligand is present, anionic ligands are written first (in alphabetical order), followed by neutral ligands (also in alphabetical order). The charge on the complex is the algebraic sum of the charge on the metal ion and the charges on the ligands. The formula is placed inside of the square brackets with the charge of the complex ion as a superscript outside the brackets. When the charge is zero the brackets and charge are omitted.

टे Predict the major products of this organic reaction. Be sure to use wedge and dash bonds when necessary, for example to distinguish between different major products. ☐ ☐ : ☐ + NaOH HO 2 Click and drag to start drawing a structure.

Shown below are five NMR spectra for five different C6H10O2 compounds. For each spectrum, draw the structure of the compound, and assign the spectrum by labeling H's in your structure (or in a second drawing of the structure) with the chemical shifts of the corresponding signals (which can be estimated to nearest 0.1 ppm). IR information is also provided. As a reminder, a peak near 1700 cm-1 is consistent with the presence of a carbonyl (C=O), and a peak near 3300 cm-1 is consistent with the presence of an O–H. Extra information: For C6H10O2 , there must be either 2 double bonds, or 1 triple bond, or two rings to account for the unsaturation. There is no two rings for this problem. A strong band was observed in the IR at 1717 cm-1
