Coordination Geometry and Hybridization in BF3-NH3 Complex
In the 1:1 complex formed between BF3 (boron trifluoride) and NH3 (ammonia), we need to analyze the coordination geometry and hybridization of both nitrogen (N) and boron (B) atoms.
Hybridization and Geometry of Nitrogen (N)
- Hybridization: NH3 has a nitrogen atom that undergoes sp3 hybridization.
- Geometry: The molecule has a trigonal pyramidal shape due to the presence of one lone pair of electrons on the nitrogen, resulting in a coordination geometry that is pyramidal.
Hybridization and Geometry of Boron (B)
- Hybridization: Boron in BF3 is sp2 hybridized. This is because boron forms three sigma bonds with fluorine atoms and has no lone pairs.
- Geometry: The molecular geometry around boron is planar with trigonal planar coordination due to the three substituents (F atoms) arranged 120 degrees apart.
Conclusion
In the BF3-NH3 complex:
- N: Pyramidal, sp3 hybridization
- B: Planar, sp2 hybridization
This leads us to the correct answer being option (c): N: pyramidal, sp3; B: planar, sp2. This complex demonstrates the interaction between a Lewis base (NH3) and a Lewis acid (BF3), resulting in the formation of a coordinate bond where the nitrogen donates a lone pair to the boron atom. Understanding these geometries is crucial in predicting the behavior and reactivity of such complexes in chemical reactions.
