Question

Most of the transition metals exhibit
(i) paramagnetic behaviour
(ii) diamagnetic behaciour
(iii) variable oxidation states
(iv) formation of coloured ions
A. (ii), (iii) and (iv)
B. (i) , (iii) and (iv)
C. (i), (ii) and (iii)
D. (i), (ii) and (iv)

Answer 1

Correct Answer - B
Due to presence of unpaired electrons in (n - 1) d-orbitals, the most of the transition metals ions coloured ions and show variable oxidation states due to presence of vacant d-orbitals.
