So benzene looks … Benzene is a planar aromatic ring, and has many representations: Regardless of whether we draw the Kekulé structure or the delocalized representation, the structure is a ring containing carbon atoms that each had formed their first bond in three directions. The molecular shape of benzene is trigonal planar. Benzene: 3D: Download 3D: Benzene was first isolated by Michael Faraday in 1825, from the whale oil used in gaslights; he also determined that it had an empirical formula of CH. Because of the aromaticity of benzene, the resulting molecule is planar in shape with each C-C bond being 1.39 Å in length and each bond angle being 120°. Modern bonding models (valence-bond and molecular orbital theories) explain the structure and stability of benzene in terms of delocalization of six of its electrons, where delocalization in this case refers to the attraction of an electron by all six carbons of the ring instead of just one or two of them. Because of the aromaticity of benzene, the resulting molecule is planar in shape with each C-C bond being 1.39 Å in length and each bond angle being 120°. Therefore, cyclohexa-1,3,5-triene is not the official IUPAC name for benzene. 4. It is because, there are no double bonds between carbon atoms in the … This delocalization causes the electrons to be more strongly held, making benzene more stable and less reactive than expected for an unsaturated hydrocarbon. As a result, the hydrogenation of benzene occurs somewhat more slowly than the hydrogenation of alkenes (other organic compounds that contain carbon-carbon double bonds), and benzene is much more difficult to oxidize than alkenes. Because of the system of delocalised electrons Benzene is also far more energetically stable than it should be, its extra stability is know as its delocalisation energy.Because of its increased stability Benzene will not readily unergo addition reactions, instead it undergoes addition reactions whereby a Hydrogen atom is replaced by another atom or group (e.g. Cyclohexane has a molecular weight of 84.16 g/mol while benzene has a molecular weight of only 78.11 g/mol.
