Question
Please I would appreciate it if I get help on all 4 questions.
1) Determine the charge on the
hexacyanoferrate(II) ion
2)Enter the formula of
Tetracarbonylnickel(0)
Use square brackets, "[" and "]", to indicate the coordination sphere.
For example, you would write Sodium Tetrachlorooxomolybdate(IV) as Na2[MoOCl4]
3) Enter the formula of
Mercury(II) tetrathiocyanatocobaltate(II)
Use square brackets, "[" and "]", to indicate the coordination sphere.
For example, you would write Sodium Tetrachlorooxomolybdate(IV) as Na2[MoOCl4]
4)The ion [Ru(CN)6]3- has one unpaired electron. [Ru(H2O)6]3+ has five unpaired electrons. Based on these results
A-Is [Ru(CN)6]3- high spin or low spin?
B-Is [Ru(H2O)6]3+ high spin or low spin?
C-Which ligand in the spectrochemical series would H2O most closely resemble? F-or en or NO2-
Explanation / Answer
1) [Fe(CN)6]4-
The charge of this ion is -4. Fe has +2 charge and CN has -1 charge. So total charge will be 2+(-1x6) = -4.
2) Formula of Tetracarbonylnickel(0) - [Ni(CO)4]
3) Formula of Mercury(II) tetrathiocyanatocobaltate(II) - Mg[Co(SCN)4]
`4) A) [Ru(CN)6]3- is low spin. Ru is in +3 oxidation state (d5) and only one unpaired electron is there. Also, CN- is a strong ligand. So the configuration should be t2g5 eg0.
B) [Ru(H2O)6]3+ is high spin. Ru is in +3 oxidation state (d5) and five unpaired electrons are there. Also, H2O is a weak ligand. So the configuration should be t2g3 eg2.
C) H2O closely resembles F- in the spectrochemical series.
