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)

(i), (iii) and (iv)

Answer 2

Due to presence of unpaired electrons in(n-1) 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.
