A) I, II and III
B) I and II
C) II and III
D) I and III
Correct Answer: A
Solution :
Colour of transition metal complex is dependent on energy difference between\[{{t}_{2g}}\]and \[{{e}_{g}}\] sets of\[d-\]orbitals, nature of ligand and type of complex formed, \[d-d\] transition is possible in \[{{d}^{1}}\] and\[{{d}^{9}}\] ions. That is why such ion complexes are coloured. On the other hand,\[{{d}^{0}}\] and \[{{d}^{0}}\] ions (such of\[Z{{n}^{2+}},\,\,T{{i}^{4+}})\] cannot show\[d-d\]transition, hence colourless.You need to login to perform this action.
