nan tne 3a orbitais 2) Identify the most likely transition metal M. There may seem to be more than one possible answer to some questions. One is more correct than the other, use your best judgement. Ks[M(CN)ol, in which M is a first row transition metal with 3 unpaired electrons b. [M(H20)s]3, in which M is a second row transition metal with LFSE -2.4 A c. [MCle, in which M is a first row transition metal with 5 unpaired electrons...
Write the formulas for the transition metal complexes
sodium hexabromoferrate(II) sodium hexafluoroaluminate dichlorobis(ethylenediamine)cobalt(III) nitrate tetraamminebromochloropatinum(IV) chloride hexaamminecobalt(III) tetrachloroferrate(III) sodium hexanitrocobaltate(III)
1.) Identify the most likely transition metal, M and provide a
suitable explanation:
a.) A complex ion with the formula
[M(H2O)6]3+, where M is a second
row transition metal, that has a LFSE (CFSE) of -2.4
(ignoring pairing and exchange energies). Hint: only the low
spin configuration is observed in second row transition metals.
b.) A tetrahedral complex ion with the formula
[MCl4]-, where M is a first row transtion
metal, that has five unpaired electrons.
Ethylenediamine is a bidentate ligand, which means it is capable of coordinating to a metal center through two sites at the same time. Click on ONE of the coordination sites in the structure of ethylenediamine: H2C-CH2 HN NHA Selected Coordinates Clear
2.(1) What does it mean when we say a transition metal complex (or a molecule) is chiral? 3.(3) Give the name or formula, as appropriate, for: a) [Co(CO)s]CO3 b) Ks[Fe(CN) 6] c) diaquabis(ethylenediamine)chromium(II) nitrate 4.(3) Give the coordination number, geometry, and hybridization of cobalt in [Co(NO2)2(en)2]2 5.(5) Draw all possible isomers of [CrNH)h(en)FJ. Label them as either geometrical or optical.
· (4 pts) Which of the following transition metal reactions is un owing transition metal reactions is unique to the Heck Reaction when compared to other transition metal-catalyzed carbon-carbon bond couplings? a. Reductive elimination b. Oxidative addition c. ß-Hydrogen elimination d. All carbon-carbon bond couplings occur by identical mechanistic steps.
Which of the following are incorrectly paired? Sr, alkaline earth metal Ir, transition metal OF, halogen Pb, transition metal Rb, alkali metal
SYNTHESIS OF TRANSITION METAL COORDINATION COM 3. Ethylenediamine ("en" in short-hand notation) has two amine groups, one at each end of a two-carbon chain, NH,CH,CH,NH. Each nitrogen in NH,CH,CH_NH, has a lone pair that coordinates to the metal. Thus, one NH CH CH NH, ligand, takes up two coordina- tion sites. a) Draw and label the structures of the cis and trans isomers of Co(en),C1,CI. b) What is the coordination number for (Coſen),C1,CI? c) Determine the oxidation state of the...
