Most of the transition metals exhibit
(i) paramagnetic behaviour
(ii) diamagnetic behaviour
(iii) variable oxidation states
(iv) coloured complexes
A.
(ii), (iii) and (iv)
B.
(i), (iii) and (iv)
C.
(i), (ii) and (iii)
D.
(i), (ii) and (iv)
Answer :
(i), (iii) and (iv)
Solution :
Due to presence of unpaired electrons in $$\left( {n - 1} \right)$$ $$d$$ - orbitals, the most of the transition metal ions and their compounds are paramagnetic. They form coloured ions and show variable oxidation states due to presence of vacant $$d$$ - orbitals.
