An element "X" of 3d series has maximuim number of unpaired electrons among all elements in its period. The element "Y" adjacent to it forms a monobasic oxyacid having tetrahedral shape.

Which is correct regarding both elements.

Options:

Answer:
D
Solution:

Identify X: Element 'X' with the maximum unpaired electrons () in the 3d series is Chromium (Cr).

 

Identify Y: Element 'Y' adjacent to Cr that forms a tetrahedral monobasic oxyacid (HMnO₄) is Manganese (Mn).

 

Evaluate (D): Y²⁺ is Mn²⁺, which has an electronic configuration of containing 5 unpaired electrons, making it strongly paramagnetic.
