Chemistry - CHEMICAL BONDING Question with Solution | TestHub
Structure of (pale yellow solid) and are given below
(It is observed that the geometry of nitrogen is planar with its surrounding atoms in structure-I.)
Select the CORRECT statements:
(A) A maximum of seven atoms may lie in one plane in structure (I).
(B) 10 atoms are sp³-hybridized in structure (I).
(C) 9 d-orbitals are involved in bonding in structure (I).
(D) The S-O bond length of FXeOSO₂F is less than the S-N bond length in FXeN(SO₂F)₂.
Options:(select one or more)
Answer:
Solution:
Statement A is correct: Since the nitrogen atom has a planar geometry, the Xe–N(S)₂ core lies in a single plane; adjusting the tetrahedral –SO₂F groups allows a maximum of 7 atoms (Xe, N, two S, and one atom from each group) to lie in that same plane.
Statement B is incorrect: Only the 2 sulfur atoms are sp³ hybridized in structure (I), whereas nitrogen is sp² hybridized due to its planar geometry.
Statement C is incorrect: The number of -orbitals involved in the bonding of the two –SO₂F groups is much fewer than 9.
Statement D is correct: Because oxygen has a smaller atomic radius and higher electronegativity than nitrogen, the S–O bond length is naturally shorter than the S–N bond length.
Conclusion: The correct options are A and D.
