Undecane (also known as hendecane) is a liquid alkane hydrocarbon with the chemical formula CH 3 (CH 2) 9 CH 3. It is used as a mild sex attractant for various types of moths and cockroaches, and an alert signal for a variety of ants. [3] It has 159 isomers. [4]
For example, if one tried to demonstrate it using the hydrocarbons decane (C 10 H 22) and undecane (C 11 H 24), one would find that 100 grams of carbon could react with 18.46 grams of hydrogen to produce decane or with 18.31 grams of hydrogen to produce undecane, for a ratio of hydrogen masses of 121:120, which is hardly a ratio of "small ...
In chemistry, a hydrocarbon is an organic compound consisting only of carbon and hydrogen. ... Petroleum (11 C, 33 P) Polycyclic nonaromatic hydrocarbons (4 C, 34 P) S.
In organic chemistry, a hydrocarbon is an organic compound consisting entirely of hydrogen and carbon. [1]: 620 Hydrocarbons are examples of group 14 hydrides. Hydrocarbons are generally colourless and hydrophobic; their odor is usually faint, and may be similar to that of gasoline or lighter fluid.
Pyrene is a polycyclic aromatic hydrocarbon (PAH) consisting of four fused benzene rings, resulting in a flat aromatic system. The chemical formula is C 16 H 10.This yellow-green solid is the smallest peri-fused PAH (one where the rings are fused through more than one face).
The adjacent diagram schematically depicts the major hydrocarbon sources and processes used in producing petrochemicals. [2] [3] [7] [8] Petrochemical feedstock sources. Like commodity chemicals, petrochemicals are made on a very large scale. Petrochemical manufacturing units differ from commodity chemical plants in that they often produce a ...
A hydrocarbon is any chemical compound that consists only of the elements carbon (C) and hydrogen (H). They all contain a carbon frame, and have hydrogen atoms attached to the frame. Often the term is used as a shortened form of the term aliphatic hydrocarbon. Most hydrocarbons are combustible. [2]
Bromine test is used to test the saturation of hydrocarbons. [17] The bromine test can also be used as an indication of the degree of unsaturation for unsaturated hydrocarbons. Bromine number is defined as gram of bromine able to react with 100g of product. [18] Similar as hydrogenation, the halogenation of bromine is also depend on the number ...
