A molecule with the formula $ \text{A} \text{X}_2 \text{Y}_2 $ has all it's elements from p-block. Element A is rarest, monotomic, non-radioactive from its group and has the lowest ionization energy value among X and Y. Elements X and Y have first and second highest electronegativity values respectively among all the known elements. The shape of the molecule is:

Element A is rarest, monotomic, non-radioactive from its group and has the lowest ionization energy value among X and Y. Elements X and Y have first and second highest electronegativity values respectively among all the known elements. The shape of the molecule is:
Show Hint
- Square pyramidal
- Octahedral
- Planar
- Tetrahedral
The Correct Option is A
Solution and Explanation
The molecule \( \text{A} \text{X}_2 \text{Y}_2 \) follows the square pyramidal structure based on the given criteria. The electronegativity and ionization energy of element A explain its rarest behavior.
