Question

Most of the transition metals exhibit:
(i) paramagnetic behaviour
(ii) diamagnetic behaviour
(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

The correct option is B (i), (iii) and (iv)

Most of the transition metals exhibit:

i) Paramagnetic Behaviour- Because of presence of unpaired e${}^{-}$s in their orbitals.

iii) Variable oxidation states- Because of vacant d-orbitals

iv) Formation of coloured ions- Because of unpaired e${}^{-}$s in their orbitals which undergoes d-d transition or charge transfer phenomenon.
