Which one of the following complexes is paramagnetic
1 \({[Co{(F)_6}]^{3 + }}\)
2 \({[Co{({H_2}O)_6}]^{3 + }}\)
3 \([Co{F_3}{({H_2}O)_3}]\)
4 All of these
Explanation:
(d) As all the ligands are weak so they do to induce pairing of electrons so they show paramagnetism.
COORDINATION COMPOUNDS
28832
The oxidation state of \(Fe\) in the complex \([Fe{(CO)_5}]\) is
1 \(-1\)
2 \(2\)
3 \(4\)
4 \(0\)
Explanation:
(d) In \([Fe{(CO)_5}],\,\,\,x + 5(0) = 0\), so oxidation number of \(Fe\) is zero.
COORDINATION COMPOUNDS
28834
The coordination and oxidation number of \(X\) in the compound \([X(S{O_4}){(N{H_3})_5}]Cl\) will be
1 \(6\) and \(4\)
2 \(10\) and \(3\)
3 \(2\) and \(6\)
4 \(6\) and \(3\)
Explanation:
(d) Co-ordination no. is \(6\) oxidation state in \([\mathop X\limits_x (\mathop {S{O_4}}\limits_{ - 2} ){(\mathop {N{H_3}}\limits_0 )_5}]\mathop {Cl}\limits_{ - 1} \) is \(x - 2 + 0 - 1 = 0,\) \(x = + 3.\)
COORDINATION COMPOUNDS
28835
In \({[NiC{l_4}]^{2 - }},\) the number of unpaired electron is
1 \(4.5\)
2 \(2\)
3 \(3\)
4 \(4\)
Explanation:
(b) \({[NiC{l_4}]^{2 - }}\) \(O.N.\) of \(Ni = +2\) \(N{i^{ + 2}}({d^8})\) \({[NiC{l_4}]^{2 - }}\) Which has two unpaired electrons that is why it is paramagnetic.
