The correct options is :
Options:
Answer:
Solution:
(P) XeO₃F₂: Xenon is sp³d hybridized (steric number 5, trigonal bipyramidal). Fluorine atoms occupy axial positions, and oxygen atoms occupy equatorial positions. This leads to a F-Xe-F bond angle of (5), and the molecule is nonpolar (4) due to the cancellation of bond dipoles. The orbital is used in sp³d hybridization (3).
(Q) SF₂(CH₃)₂: Sulfur is sp³d hybridized (steric number 5, trigonal bipyramidal). The lone pair and fluorine atoms occupy equatorial positions, while the methyl groups occupy axial positions. The orbital is used (3). The central S atom, two axial CH₃ groups, and two equatorial F atoms can lie in the same plane (1).
(R) XeO₂F₄: Xenon is sp³d² hybridized (steric number 6, octahedral). The oxygen atoms are trans to each other, and the fluorine atoms are in the equatorial plane. This highly symmetrical structure has a zero dipole moment (4) and bond angles (5). Both (2) and (3) orbitals are used in sp³d² hybridization. The Xe atom and four F atoms lie in the same plane (1).
(S) FXeOSO₂F: Around Xenon, the steric number is 5 (2 sigma bonds, 3 lone pairs), leading to sp³d hybridization and a linear F-Xe-O arrangement, thus a bond angle (5). The orbital is used (3). Due to its complex structure, it is possible for 5 atoms to lie in the same plane (1).
