  • Alkane - Wikipedia
    In organic chemistry, an alkane, or paraffin (a historical trivial name that also has other meanings), is an acyclic saturated hydrocarbon In other words, an alkane consists of hydrogen and carbon atoms arranged in a tree structure in which all the carbon–carbon bonds are single [1]
  • Alkanes - Chemistry LibreTexts
    The distinguishing feature of an alkane, making it distinct from other compounds that also exclusively contain carbon and hydrogen, is its lack of unsaturation That is to say, it contains no double or triple bonds, which are highly reactive in organic chemistry
  • Alkanes: Formulas, Structures, and Reactions - ChemTalk
    Alkanes are the most basic compounds in Organic Chemistry However, they are also very important as they form the backbones of many other complex compounds In this article, you will learn about the structure of alkane, its nomenclature, and some of its reactions
  • Alkanes- Definition, Structure, Properties, Reactions, Uses
    Sodium salt of carboxylic acid when heated with soda lime (NaOH+CaO) alkane is formed Thus, a produced alkane consists of one carbon less than the original acid
  • What are Alkanes? - BYJUS
    In a long chain alkane molecule, additional carbon atoms are attached to each other with the help of a single covalent bond Each atom is attached to the sufficient hydrogen atoms to develop a total of four single covalent bonds This long-chain structure is known as octane
  • Alkanes, Alkenes, and Alkynes Explained
    Alkanes, also known as paraffins, are the simplest type of hydrocarbons They are composed only of carbon (C) and hydrogen (H) atoms, connected by single covalent bonds Each carbon atom in an alkane is sp³ hybridized, meaning it forms four single bonds in a tetrahedral arrangement
  • Alkane Formula [with free study guide] - Ace Organic Chem
    An alkane is a simple hydrocarbon containing carbon and hydrogen single bonded to each other, with a carbon backbone Any molecule with this structure is going to have the formula C n H n+2, where n is any integer
  • Alkanes - HyperPhysics
    Hydrocarbons which contain only single bonds are called alkanes They are called saturated hydrocarbons because there is a hydrogen in every possible location This gives them a general formula C n H 2n+2 The first four alkanes are methane, ethane, propane, and butane with the Lewis symbols shown below
