How many bonds does the benzene ring have, and how many bonds does the benzene ring have?

Although the structure of the benzene ring drawn by Kekuler is a three-single and three-double structure, the benzene ring actually has six bonds and a six-center, six-electron delocalized large bond.

There are 12 bonds formed between carbon and hydrocarbon and 1 large bond formed by six carbon atoms on the benzene ring. ‍

The benzene ring is the simplest aromatic ring, which consists of six carbon atoms to form a six-membered ring, each carbon atom is connected to a group, and the 6 groups of benzene are all hydrogen atoms. The benzene ring is a closed conjugated system, and the electron cloud distribution of the six carbon atoms is the same. But when there is a substituent on the benzene ring, the substituent changes the electron distribution of the benzene ring, polarizing the molecule.

Benzene ring valence bond view

The cyclic olefin with a carbon number of 4n+2 (n is a positive integer, benzene is n=1) and has an alternating structure of single and double bonds is called annulene, and benzene is a kind of cyclene (annulene). The benzene molecule is a planar molecule, 12 atoms are in the same plane, 6 carbon and 6 hydrogen are equal, the c-h bond length is, and the c-c bond length is, which is between the single and double bond lengths. All bond angles in the molecule are 120° and the carbon atoms are sp2 hybridized.

Each carbon atom also has one p orbital left perpendicular to the molecular plane and one electron in each orbital. The six orbitals overlap to form a delocalized bond, and the resonance hybrid theory proposed by Linus Pauling believes that the resonance hybrid of benzene is the reason for the very stability of the benzene ring, which also directly leads to the aromaticity of the benzene ring.

The major bond of benzene refers to the bond between two adjacent carbon atoms in the benzene molecule, which is composed of a covalent bond between two carbon atoms and a bond between two carbon atoms. It is a strong covalent bond that is much stronger than a normal covalent bond.

The large bond of benzene is a special bond, except for jujube, which is made up of six atoms, one carbon atom and five hydrogen atoms. Its peculiarity lies in the fact that its six atoms form a plane, and this plane is a circle, which is why it is called a large bond.

The function of the big bond is that it can connect the six atoms of a molecule to form a stable molecular structure. It is a very important structure that can be used to build many organic molecules, such as fatty acids, proteins, and nucleic acids.

Large bonds can also be used to construct very complex molecules, such as organic dyes, pharmaceuticals, and polymer materials. They can be used to make new materials, such as polymers, composites, and nanomaterials.

Each of the 6 carbon atoms on the benzene ring has 1 unhybridized 2p orbital, which is perpendicular to the plane of the ring and overlaps each other from the sides to form a closed bond, and is evenly distributed symmetrically above and below the plane of the ring. This bond type of benzene is usually called a large bond. Wild talk.

The electrons of the six carbon atoms in the benzene molecule overlap each other with sp 2 hybrid orbitals to form six carbon-carbon bonds, and each overlap with the 1s orbital of hydrogen atoms with one sp 2 hybrid orbital to form six hydrocarbon bonds. Since it is sp2 hybridized, the bond angle is 120° and all the 6 carbon atoms and 6 hydrogen atoms are connected to each other in the same plane.

The big bonds of benzene

is evenly distributed over six carbon atoms, so the bond length and bond energy of each carbon-carbon bond in the benzene molecule are equal.

For another example, the molecular formula of 1,3-butadiene is H2C=CH-CH= carbon atoms are adjacent to 3 atoms, so sp2 hybridization is used. These hybrid orbitals overlap each other to form a molecular backbone, so all atoms are in the same plane. Each carbon atom also has a p-orbital that is not involved in hybridization, perpendicular to the molecular plane, and there is one electron in each p-orbital, so there is a p-p bond of "4 orbitals and 4 electrons" in the butadiene molecule.

It is usually expressed by ab, where a is the number of parallel p orbitals and b is the number of electrons in parallel p orbitals.
