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]
Those who wish to adopt the textbooks are required to send a request to NCERT, upon which soft copies of the books are received. The material is press-ready and may be printed by paying a 5% royalty, and by acknowledging NCERT. [11] The textbooks are in color-print and are among the least expensive books in Indian book stores. [11]
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).

Petroleum ether should not be confused with the class of organic compounds called ethers; and equally, going under its alternative name of benzine, it should not be confused with benzene. (Benzine is a mixture of alkanes, such as pentane, hexane, and heptane; whereas benzene is a cyclic, aromatic hydrocarbon.)
But there lies the deeper problem. Hexane refers both to a specific compound (n-hexane), but also to a class of compounds, more generally, the C6 unsaturated hydrocarbons. ("That compound is a hexane. And that compound too is a hexane.")
Icosane (alternative spelling eicosane and eichosane [2]) is an alkane with the chemical formula C 20 H 42.It has 366,319 constitutional isomers.. n-Icosane (the straight-chain structural isomer of icosane) is the shortest compound found in paraffin waxes used to form candles.
A non-Kekulé molecule is a conjugated hydrocarbon that cannot be assigned a classical Kekulé structure [definition needed]. Since non-Kekulé molecules have two or more formal charges or radical centers, their spin-spin interactions can cause electrical conductivity or ferromagnetism ( molecule-based magnets ), and applications to functional ...
