This implies that electrons are evenly distributed, which in turn leads to even distribution of charges in this aromatic compound. Structure of the benzene molecule. In 1866, August Kekulé used the principles of structural theory to postulate a structure for the benzene molecule. Kekulé based his postulation on the following premises: The molecular formula for benzene is C 6 H 6. All the carbons have four bonds as predicted by structural theory.

Most chemists were quick to accept this structure, since it accounted for most of the known isomeric relationships of aromatic chemistry. The hexagonal structure explains why only one isomer of benzene exists and why disubstituted compounds have three isomers. Benzene has a cyclic structure with C-C double bonds. Hydrogen lies on the outer side of the ring structure. This implies that electrons are evenly distributed, which in turn leads to even distribution of charges in this aromatic compound. Structure of the benzene molecule.

The Structure and Geometry of Benzene. All the carbon atoms in benzene are sp 2 hybridized connected by sp2 – sp2 single bonds and each has a p orbital perpendicular to the plane of the atoms. These p orbitals overlap, delocalizing the six electrons and making benzene a fully conjugated system. The geometry of each carbon is trigonal planar:

This baffled chemists because carbon is known to be tetravalent. This means that every carbon atom is capable of chemical bonds with four other atoms.

Benzene is one of the most commonly known aromatic compounds with chemical formula C6H6. To study the hexagonal ring structure of benzene along with its

On the basis of these facts, in 1865 August Kekule proposed the structure of Benzene in which the six carbon atoms were arranged to form a hexagonal ring with each carbon atom carrying one hydrogen atom.

(Chloromethyl)benzene CAS Number: 25168-05-2: Molecular Weight: 126.58300: Density: 0.968g/cm3: Boiling Point: 173.6ºC at 760mmHg: Molecular Formula: C 7 H 7 Cl: Melting Point: N/A: MSDS: N/A Flash Point: 51.7ºC

Building the orbital model. Benzene is built from hydrogen atoms (1s 1) and carbon atoms (1s 2 2s 2 2p x 1 2p y 1).. Each carbon atom has to join to three other atoms (one hydrogen and two carbons) and doesn't have enough unpaired electrons to form the required number of bonds, so it needs to promote one of the 2s 2 pair into the empty 2p z orbital.
