"In organic chemistry, an alkane, or paraffin (a historical trivial name that also has other meanings), is an acyclic saturated hydrocarbon."
Learning about the properties and reactions of alkanes, including combustion reactions and substitution reactions.
"An alkane consists of hydrogen and carbon atoms arranged in a tree structure in which all the carbon–carbon bonds are single."
"Alkanes have the general chemical formula CnH2n+2."
"The simplest case of methane (CH4), where n = 1 (sometimes called the parent molecule)."
"Yes, alkanes can range from arbitrarily large and complex molecules, like pentacontane (C50H102) or 6-ethyl-2-methyl-5-(1-methylethyl) octane."
"The IUPAC defines alkanes as 'acyclic branched or unbranched hydrocarbons having the general formula CnH2n+2, and therefore consisting entirely of hydrogen atoms and saturated carbon atoms'."
"Some sources use the term to denote any saturated hydrocarbon, including those that are either monocyclic (i.e. the cycloalkanes) or polycyclic, despite their having a distinct general formula (i.e. cycloalkanes are CnH2n)."
"In an alkane, each carbon atom is sp3-hybridized with 4 sigma bonds (either C–C or C–H), and each hydrogen atom is joined to one of the carbon atoms (in a C–H bond)."
"The longest series of linked carbon atoms in a molecule is known as its carbon skeleton or carbon backbone."
"One group of the higher alkanes are waxes, solids at standard ambient temperature and pressure (SATP), for which the number of carbon atoms in the carbon backbone is greater than about 17."
"With their repeated –CH2 units, the alkanes constitute a homologous series of organic compounds in which the members differ in molecular mass by multiples of 14.03 u."
"Methane is produced by methanogenic bacteria and some long-chain alkanes function as pheromones in certain animal species or as protective waxes in plants and fungi."
"The alkanes have two main commercial sources: petroleum (crude oil) and natural gas."
"An alkyl group is an alkane-based molecular fragment that bears one open valence for bonding."
"They are generally abbreviated with the symbol for any organyl group, R, although Alk is sometimes used to specifically symbolize an alkyl group (as opposed to an alkenyl group or aryl group)." Note: Only 15 questions were generated as input, so only 15 outputs are provided.
