Question

What is the axmen classification for benzene (C6H6)?

Answer 1

Answer is: Benzene is trigonal (or triangular) planar.

VSEPR theory (The Valence Shell Electron Pair Repulsion Theory) uses the AXE notation (m and n are integers, m + n = number of regions of electron density).

For benzene molecule (C₆H₆):

m = 3; the number of atoms bonded to the central atom.

n = 0; the number of lone pairs on the central atom.

Answer 2

The${\text{A}}{{\text{X}}_{\text{m}}}{{\text{E}}_{\text{n}}}$classification for each carbon in benzene is ${\text{A}}{{\text{X}}_{\text{3}}}$.

Further explanation:

VSEPR Theory:

The VSEPR theory is also known as valence shell electron pair repulsion theory. This theory is used to determine the geometry of a central atom or ion. It is based on the repulsion between bond pairs and lone pair in the valence shell of the central atom.

The ${\text{A}}{{\text{X}}_{\text{m}}}{{\text{E}}_{\text{n}}}$classification is used to expresses the geometry of the central atom in VSEPR theory. In ${\text{A}}{{\text{X}}_{\text{m}}}{{\text{E}}_{\text{n}}}$classification, A is a central atom, X is covalent bond, E is the lone pair, m is the total number of covalent bond present on central atom, and n is the total number of lone pair present on central atom.

Since ${\text{A}}{{\text{X}}_{\text{m}}}{{\text{E}}_{\text{n}}}$classification is only calculated for the central atoms and benzene contains 6 central carbon atoms thus we can calculate ${\text{A}}{{\text{X}}_{\text{m}}}{{\text{E}}_{\text{n}}}$classification of each central carbon atom.

In benzene, each carbon atom has 4 valence electrons. These 4 valence electron is are used in forming 3 covalent bonds, one C-H single bond, one C-C single bond, and one C=C double bond. Therefore, the value of m is 3. There is no lone pair on any central carbon atom thus the value of n is zero.

Therefore the configuration for each carbon in benzene is ${\text{A}}{{\text{X}}_{\text{3}}}$.
