Chapter 11, Problem 11.1P

(a)

Interpretation Introduction

Interpretation:

The hybridization of the central atom that corresponds to a trigonal planar arrangement is to be determined.

Concept introduction:

The atomic orbital is the wave function that is used to find the probability to find an electron around the nucleus of an atom. It is the space around the nucleus of an atom where the electrons are supposed to be found.

Hybridization is the process of intermixing of atomic orbital of slightly different energies to form hybrid orbitals that have similar energy. These orbital have lower energy and more stability than the atomic orbital.

Answer to Problem 11.1P

The hybridization of the central atom in trigonal planar is sp2.

Explanation of Solution

The molecule that has trigonal planar geometry is BF3. The atomic number of boron is 5 so its electronic configuration is 1s22s22p1.

The partial orbital diagram of an isolated B atom is as follows:

The partial orbital diagram of a hybridized B atom is as follows:

CHEM 212:CHEMISTSRY V 2, Chapter 11, Problem 11.1P , additional homework tip  2

The half-filled sp2 orbitals are filled with three electrons of three fluorine atoms. So the hybridization of B in BF3 is sp2.

Conclusion

The hybridization of the central atom in trigonal planar is sp2.
