The following is a list of straight-chain alkanes, the total number of isomers of each (including branched chains), and their common names, ... 4.836 166 718 988 32 ...
Alkanes have the general chemical formula C n H 2n+2. The alkanes range in complexity from the simplest case of methane (CH 4), where n = 1 (sometimes called the parent molecule), to arbitrarily large and complex molecules, like pentacontane (C 50 H 102) or 6-ethyl-2-methyl-5-(1-methylethyl) octane, an isomer of tetradecane (C 14 H 30).
In organic chemistry, an alkyl group is an alkane missing one hydrogen. [1] The term alkyl is intentionally unspecific to include many possible substitutions. An acyclic alkyl has the general formula of −C n H 2n+1. A cycloalkyl group is derived from a cycloalkane by removal of a hydrogen atom from a ring and has the general formula −C n H ...
The dialkylating group is often a 1,3-, 1,4-, etc. dihalide. [9] In some cases the dialkylating group is a dilithio reagent, such as 1,5-dilithiopentane. [ 10 ] For generating spirocycles containing a cyclopropane ring, cyclopropanation with cyclic carbenoids has been demonstrated.
The naming of polycyclic alkanes such as bicyclic alkanes and spiro alkanes is more complex, with the base name indicating the number of carbons in the ring system, a prefix indicating the number of rings ( "bicyclo-" or "spiro-"), and a numeric prefix before that indicating the number of carbons in each part of each ring, exclusive of ...
Tetra-tert-butylmethane is a hypothetical organic compound with formula C 17 H 36, consisting of four tert-butyl groups bonded to a central carbon atom.It would be an alkane, specifically the most compact branched isomer of heptadecane.
Alkanes as substituents are called alkyl groups Subcategories. This category has the following 5 subcategories, out of 5 total. B. Butane (2 C, 11 P) E. Ethane (1 C ...
The smallest alkane with such a chemical bond, ethane, exists as an infinite number of conformations with respect to rotation around the C–C bond. Two of these are recognised as energy minimum ( staggered conformation ) and energy maximum ( eclipsed conformation ) forms.
