Question

Consider the molecule BF3. (a) What is the electron config- uration of an isolated B atom? (b) What is the electron con- figuration of an isolated F atom? (c) What hybrid orbitals should be constructed on the B atom to make the B–F bonds in BF3? (d) What valence orbitals, if any, remain unhybrid- ized on the B atom in BF3?

Answer 1

For the given molecule, we are asked to give-

1. The electron configuration of an isolated B atom
2. The electron configuration of an isolated F atom
3. Hybrid orbitals should be constructed on the B atom to make the B–F bonds in Boron tri flouride
4. valence orbitals, if any, remain unhybridized on the B atom.

• The electron configuration of an isolated B atom:

as atomic number of B is 5

electronic configuration will be [He] 2s² 2p¹

• The electron configuration of an isolated F atom:

as atomic number of F is 9

electronic configuration will be  [He] 2s² 2p5

• Hybrid orbitals should be constructed on the B atom to make the B–F bonds in Boron tri flouride will be sp2.

as the one s and two of p orbital from the valance shell will hybridised to make 3 hybrid orbital of B resulting in 3 B-F bonds.

• valence orbitals, if any, remain unhybridized on the B atom will be 1
