Question

[Cr(NH3)(H2O)4Cl]Br2 is:

If the atomic orbital below corresponds to a first row transition metal, what are the principal quantum number, n, and the angular momentum quantum number, l? orbitals_2.jpg n = 3 and l = 0 n = 3 and l = 3 n = 3 and l = 2 n = 3 and l = 1 Which of the ligands drawn below are monodentate ligands? (c) and (d) (a) and (b) All are monodentate. None are monodentate. I think the answer is A but im not sure why D is a monodentate ligand. Which of the following statements regarding ligands is correct? All ligands are Lewis bases. Positive ions make good ligands. The atom bonding to the metal is positively polarized. Only one atom of the ligand can bond to the metal. All ligands are negative ions. Which one of the following coordination complexes would you expect to be the most stable (having the highest formation constant)? [Co(NH3)6]3+ [CoF6]3â [Co(en)3]3+ [Co(EDTA)]â What is the oxidation number of Mo in (NH4)2[MoS4]? A coordination compound formed from chromium(III) chloride contains five ammonia molecules andone water molecule which function as ligands. The formula of the compound is properly written as The systematic name for [Cr(NH3)(H2O)4Cl]Br2 is: amminetetraaquachlorochromium(III) bromide None of these is correct chromium(III)amminetetraaquachloro bromide chromiumamminetetraaquachlorine(I) bromide chromiumamminetetraaquachlorine(III) bromide
