(a)
COORDINATION COMPOUNDS
28804
The coordination number and oxidation state of \(Cr\) in \({K_3}\left[ {Cr{{\left( {{C_2}{O_4}} \right)}_3}} \right]\) are, respectively
1 \(4\) and \(+2\)
2 \(6\) and \(+3\)
3 \( 3 \) and \( +3\)
4 \(3\) and \( 0\)
Explanation:
(b)Its coordination number will be \( 6\) because it is bonded with three bidentale ligands. Oxi. No. of \(Cr\) in \(\mathop {{K_3}}\limits_{ - 1} [Cr\mathop {{{({C_2}{O_4})}_3}}\limits_{ - 2} ]\) is \(x + 3( - 2) + 3( + 1) = 0\) \( \Rightarrow \,\,x = + 3\)
