Benzene example sentences

Therefore, –OH group activates the benzene ring for the attack by an electrophile.The orbital overlapping gives us better picture about the structure of benzene.All the six carbon atoms in benzene are sp2 hybridized.Benzene was found to be a stable molecule and found to form a triozonide which indicates the presence of three double bonds.Benzene ring is highly unsaturated but in a majority of reactions of aromatic compounds, the unsaturation of benzene ring is retained.In this case, the overall electron density on benzene ring decreases making further substitution difficult, therefore these groups are also called 'deactivating groups'.The nomenclature and isomerism of aromatic hydrocarbons has already been discussed in Unit 1 All six hydrogen atoms in benzene are equivalent; so it forms one and only one type of monosubstituted product.When two hydrogen atoms in benzene are replaced by two similar or different monovalent atoms or groups, three different position isomers are possible.Benzene was further found to produce one and only one monosubstituted derivative which indicated that all the six carbon and six hydrogen atoms of benzene are identical.The Kekulé structure indicates the possibility of two isomeric 1, 2-dibromobenzenes.Have you perceived the idea of green chemistry ? It is well known that organic solvents such as benzene, toluene, carbon tetrachloride etc.He gave the dynamic structural formula to benzene which forms the basis for its modern electronic structure.Therefore, presence of delocalised ? electrons in benzene makes it more stable than the hypothetical cyclohexatriene.Even with this modification, Kekulé structure of benzene fails to explain unusual stability and preference to substitution reactions than addition reactions, which could later on be explained by resonance.Because of their strong – I effect, overall electron density on benzene ring decreases.
