Q27 / 105 · NTA Abhyas (JEE Main) 2020 · Chemistry · d and f Block Elements

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)
  • Correct answer
    B
    (i), (iii) and (iv)
  • C
    (i), (ii) and (iii)
  • D
    (i), (ii) and (iv)

Solution

Due to presence of unpaired electrons in n-1d 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.

Hence, the correct answer is option: 'B'.
