NEET Chemistry Properties of d-block MCQ Question
Which of the following combinations about the properties of d-block elements are correct?
d-block elements exhibit variable oxidation states, can form complex ions, and are generally good conductors of electricity.
All d-block elements have completely filled d-orbitals in their stable states, leading to unique magnetic properties.
The ionisation enthalpies of d-block elements increase consistently across the series due to their increasing atomic size.
d-block elements primarily form ionic bonds, and their compounds are always soluble in water.
Correct Answer
Detailed Explanation
d-block elements indeed exhibit variable oxidation states and can form complex ions, which contributes to their properties as good conductors of electricity. The other options contain misconceptions about the electronic configurations and bonding nature of d-block elements.
