Octane is a hydrocarbon and also an alkane with the chemical formula C 8 H 18, and the condensed structural formula CH 3 (CH 2) 6 CH 3.Octane has many structural isomers that differ by the location of branching in the carbon chain.
2,2,4-Trimethylpentane, also known as isooctane or iso-octane, is an organic compound with the formula (CH 3) 3 CCH 2 CH(CH 3) 2. It is one of several isomers of octane (C 8 H 18 ). This particular isomer is the standard 100 point on the octane rating scale (the zero point is n -heptane ).
Tetramethylbutane, sometimes called hexamethylethane, is a hydrocarbon with formula C 8 H 18 or (H 3 C-) 3 C-C(-CH 3) 3.It is the most heavily branched and most compact of the octane isomers, the only one with a butane (C4) backbone.
In chemistry, the lever rule is a formula used to determine the mole fraction (x i) or the mass fraction (w i) of each phase of a binary equilibrium phase diagram.It can be used to determine the fraction of liquid and solid phases for a given binary composition and temperature that is between the liquidus and solidus line.
A chemical equation is the symbolic representation of a chemical reaction in the form of symbols and chemical formulas.The reactant entities are given on the left-hand side and the product entities are on the right-hand side with a plus sign between the entities in both the reactants and the products, and an arrow that points towards the products to show the direction of the reaction.

The growth of the hydrocarbon chain may be visualized as involving a repeated sequence in which hydrogen atoms are added to carbon and oxygen, the C–O bond is split and a new C–C bond is formed. For one –CH 2 – group produced by CO + 2 H 2 → (CH 2) + H 2 O, several reactions are necessary: Associative adsorption of CO; Splitting of ...
The Ellingham diagram plots the Gibbs free energy change (ΔG) for each oxidation reaction as a function of temperature. For comparison of different reactions, all values of ΔG refer to the reaction of the same quantity of oxygen, chosen as one mole O (1 ⁄ 2 mol O 2) by some authors [2] and one mole O 2 by others. [3] The diagram shown ...
2 mixture by knowing the partial pressure of each species and the value of K eq. For instance, in a high temperature reducing environment, such as that created for the reduction of iron oxide in a blast furnace or the preparation of carburizing atmospheres, [ 5 ] carbon monoxide is the stable oxide of carbon.
