WebNov 24, 2024 · What are alkanes BBC Bitesize? Alkanes are saturated hydrocarbons. This means that their carbon atoms are joined to each other by single bonds. This makes them relatively unreactive, apart from their reaction with oxygen in the air – which we call burning or combustion. Butane. Like other homologous series, the alkanes show isomerism.

WebMost of the hydrocarbons in crude oil are hydrocarbons called alkanes. The general formula for the homologous series of alkanes is C₂H₂ₙ₊₂; The first four members of the alkanes are methane, ethane, propane and butane. Alkane molecules can be represented in the following forms: (C₂H₆ or drawn out version). WebAlkanes can undergo free-radical substitution in which a hydrogen atom gets substituted by a halogen (chlorine/bromine) Since alkanes are very unreactive, ultraviolet light (sunlight) is needed for this substitution reaction to occur. The free-radical substitution reaction consists of three steps: In the initiation step, the halogen bond (Cl-Cl ...

Alkanes are organic compounds that consist entirely of single-bonded carbon and hydrogen atoms and lack any other functional groups. Alkanes have the general formula CnH2n+2 C n H 2 n + 2 and can be subdivided into the following three groups: the linear straight-chain alkanes, branched alkanes, and cycloalkanes.
WebThe alkanes are saturated. hydrocarbons: Hydrocarbons, because they are compounds containing hydrogen and carbon only. Saturated, because they only contain single bonds.
