The correct Answer is:
To determine in which of the given compounds all fluorine atoms are in the same plane, we will analyze the molecular geometry of each compound provided in the options. ### Step-by-Step Solution: 1. **Analyzing CHF3 (Chloroform)** - The central atom is carbon (C). - Carbon is bonded to three fluorine (F) atoms and one hydrogen (H) atom. - The molecular geometry around carbon is tetrahedral due to the four substituents. - However, since hydrogen is less electronegative, it will be positioned above the plane formed by the three fluorine atoms. - **Conclusion**: All three fluorine atoms are in the same plane. 2. **Analyzing CIF3 (Chlorine Trifluoride)** - The central atom is chlorine (Cl). - Chlorine is bonded to three fluorine (F) atoms and has one lone pair. - The molecular geometry is also tetrahedral due to the four regions of electron density (three F atoms and one lone pair). - The lone pair will occupy one position, and the three fluorine atoms will be arranged in a plane. - **Conclusion**: All three fluorine atoms are in the same plane. 3. **Analyzing XeOF4 (Xenon Oxyfluoride)** - The central atom is xenon (Xe). - Xenon is bonded to one oxygen (O) atom (with a double bond) and four fluorine (F) atoms. - The molecular geometry is square planar due to the arrangement of four fluorine atoms around xenon. - In a square planar geometry, all four fluorine atoms lie in the same plane. - **Conclusion**: All four fluorine atoms are in the same plane. 4. **Final Conclusion** - Since all three compounds (CHF3, CIF3, and XeOF4) have their fluorine atoms in the same plane, the correct answer is: - **Option D: All of the above.**
