Hydrocarbon - Structure, Bonding, Compounds | Britannica
2024年11月21日 · The true structure of benzene is described as a hybrid of the two Kekule forms and is often simplified to a hexagon with an inscribed circle to represent the six delocalized π electrons. It is commonly said that a resonance hybrid is more stable than any of the contributing structures, which means, in the case of benzene, that each π electron ...

2024年11月21日 · Hydrocarbon - Structures, Bonds, Compounds: Most organic molecules, including all alkanes, are not planar but are instead characterized by three-dimensional structures. Methane, for example, has the shape of a regular tetrahedron with carbon at the centre and a hydrogen atom at each corner.

Hydrocarbon - Chemical Reactions | Britannica
2024年11月21日 · Hydrocarbon - Chemical Reactions: As is true for all hydrocarbons, alkanes burn in air to produce carbon dioxide (CO2) and water (H2O) and release heat. The combustion of 2,2,4-trimethylpentane is expressed by the following chemical equation: The fact that all hydrocarbon combustions are exothermic is responsible for their widespread use as fuels.
