Which of the following ligands has a negative charge?  (The formulas shown do not necessarily have the correct charges.) Group of answer choices cyclooctatetraene (C8H8) cyclooctadiene (COD) cyclobutadiene (C4H4) methyl (CH3)

Both A) NH3, ammonia, and C) CN-, cyanide are incorrect, please help

Organometallics A. For the following metal complexes indicate: 1) the metal oxidation state, il) the d- electron count, iii) the valence electron count for the complex, iv) the expected metal geometry, and v) draw the complex. (NB: A periodic table is provided on the last page) [Ru(CH)C₂1₂ VO(acac), Oxidation State: +2 +4 d electrons Valence e Geometry Structure [( dppe )Co(CH) [(CH)Y(H)Phol, Oxidation State: d electrons Valence e Geometry Structure 6 5 5

A hypothetical metal M forms the following complexes with the generalized ligands X, Y, and Z:   Complex ion Observed color [M(X)6]3+ green [M(Y)6]3+ blue [M(Z)6]3+ yellow Order these ligands according to their ability to split d orbitals. In other words, set up a spectrochemical series, from strongest to weakest ligand field strength. Rank from strongest to weakest ligand field strength.    -X -Z -Y

Match the orbitals below to the higher and lower energy levels when an octahedral complex undergoes ligand field splitting. dx2-y2 Orbital 1 Orbital 1 Orbital 2 Orbital 3 Orbital 4 Orbital 5 L d₂2 Orbital 2 L dyz Orbital 3 dxz Orbital 4 [Choose] ◊ [Choose] ↑ [Choose] ◊ [Choose] [Choose] ↑ L dxy Orbital 5

oving to another question will save this response. complex [Co(NH3)6l absorbs light at a wavelength of 465 nm. What is the ligand field aplitting energy for the cormplez in Jlaole? 275 x 10 to negative x AMoving to another question will save this response.

Giving at least 2 reasons, predict whether [Co(OH2)6]2+ or [Co(NCS)4]2- has a higher Kstab.

Are structures for all of the possible isomers of six coordinate compounds [Co(NH3)4Cl2] and[Co(NH3)3Cl3].
