JEE Mains · Chemistry · STD 11 - 4. Chemical bonding and molecular structure
A molecule with the formula \(\mathrm{AX}_4 \mathrm{Y}\) has all it's elements from p-block. Element A is rarest, monoatomic, non-radioactive from its group and has the lowest ionization enthalpy value among A, 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 :
- A Square pyramidal
- B Octahedral
- C Pentagonal planar
- D Trigonal bipyramidal
Answer & Solution
Correct Answer
(A) Square pyramidal
Step-by-step Solution
Detailed explanation
Given A is rarest, monoatomic, non-radioactive p-block element and form \(\mathrm{AX}_4 \mathrm{Y}\) type of molecule. \(\therefore\) It is concluded that it is Xe It is given the electronegativity of A is less than X & Y It is given the electronegativity of…
