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

Answer: (B)

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 also due to presence of vacant d-orbitals.
