Alkanes: Kinetics and Rate

Most reactions require the addition of energy. Energy is needed for molecules to pass over the energy barriers that separate them from becoming reaction products. These energy barriers are called the activation energy, or enthalpy of activation, of the reactions. At room temperature, most molecules have insufficient kinetic energy to overcome the activation energy barrier so a […]


Alkanes: Halogenation

The reaction of a halogen with an alkane in the presence of ultraviolet (UV) light or heat leads to the formation of a haloalkane (alkyl halide). An example is the chlorination of methane. Experiments have shown that when the alkane and halogen reactants are not exposed to UV light or heat, the reaction does not occur. However, […]


Molecular and Structural Formulas of ALKANES

The alkanes comprise a series of compounds that are composed of carbon and hydrogen atoms with single covalent bonds. This group of compounds comprises a homologous series with a general molecular formula of C n H 2 n+2 , where equals any integer. The simplest alkane, methane, has one carbon atom and a molecular formula of CH 4. Because this compound […]
