In organic chemistry, pentadiene is any hydrocarbon with an open chain of five carbons, connected by two single bonds and two double bonds. All those compounds have the same molecular formula C 5 H 8. The inventory of pentadienes include: 1,2-pentadiene, or ethyl allene, H 2 C=C=CH−CH 2 −CH 3. [1] 1,3-pentadiene, H 2 C=CH−CH=CH−CH 3 ...
In physics, there are equations in every field to relate physical quantities to each other and perform calculations. Entire handbooks of equations can only summarize most of the full subject, else are highly specialized within a certain field. Physics is derived of formulae only.
Pentane is an organic compound with the formula C 5 H 12 —that is, an alkane with five carbon atoms. The term may refer to any of three structural isomers, or to a mixture of them: in the IUPAC nomenclature, however, pentane means exclusively the n-pentane isomer, in which case pentanes refers to a mixture of them; the other two are called isopentane (methylbutane) and neopentane ...
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).
The reaction 2 H 2 + O 2 → 2 H 2 O provides an example of chain branching. The propagation is a sequence of two steps whose net effect is to replace an H atom by another H atom plus two OH radicals. This leads to an explosion under certain conditions of temperature and pressure. [6] H• + O 2 → •OH + •O•
