Science / Chemistry / Alkane: A series of organic compounds with general formula CnH2n+2. Alkane names end with -ane. Examples are propane (with n=3) and octane (with n=8).


Science / Chemistry / Octane: Flammable liquid compounds found in petroleum and natural gas. There are 18 different octanes- they have different structural formulas but share the molecular formula C8H18. Octane is used as a fuel a MORE


Science / Chemistry / Alkyl: (-cnh2n+1) alkyl group. A molecular fragment derived from an alkane by dropping a hydrogen atom from the formula. Examples are methyl (CH3) and ethyl (CH2CH3). MORE


Science / Chemistry / Propane: A colorless, odorless, flammable gas, found in petroleum and natural gas. It is used as a fuel and as a raw material for building more complex organic molecules. Propane is the third member of the alk MORE


Science / Chemistry / Paraffin: 1. A waxy substance that is a mixture of alkanes with chains containing 18 to 36 carbon atoms. 2. An alkane. MORE


Science / Chemistry / Hydrocarbon: Hydrocarbons are organic compounds that contain only hydrogen and carbon. The simplest hydrocarbons are the alkanes. MORE

Polar Molecule

Science / Chemistry / Polar Molecule: An asymmetric molecule containing polar bonds. H2O, NH3, and hcl are examples of polar molecules. Non-examples are CO2, ccl4, and bcl3 which contain polar bonds but are nonpolar because they have symm MORE
