NEET Chemistry Properties of d-block MCQ Question
Which of the following statements about the properties of the d-block elements are correct?
The magnetic susceptibility of actinoids is generally lower than that of lanthanoids.
Manganese (II) ions can be oxidised to permanganate using peroxodisulphate.
Potassium permanganate is very soluble in water at room temperature.
The actinoids react vigorously with boiling water to form only hydrides.
Correct Answer
Detailed Explanation
Statement B is correct as manganese (II) ions can be oxidised to permanganate using peroxodisulphate. Statement A is incorrect because the magnetic susceptibility of actinoids is more complex and generally higher than that of lanthanoids. Statement C is incorrect since potassium permanganate has low solubility in water. Statement D is incorrect as actinoids form a mixture of oxide and hydride when reacting with boiling water.
